*** PLEASE WATCH WITH ANNOTATIONS ON! SOME INACCURACIES IN GRAPHICS ARE NOTED AND CORRECTED IN ANNOTATIONS. THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

Polar Molecules Tutorial: How to determine polarity in a molecule
 
10:36
This video looks at how to determine polarity in a molecule by understanding how the bond polarities, molecule shape, and outside atoms influence polarity using bond polarity vector addition. This includes a flow chart that guides you through the various decisions needed to determine if a molecule is polar or not. Wikipedia 1/1/2018: In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have a geometry which is asymmetric in at least one direction, so that the bond dipoles do not cancel each other. While the molecules can be described as "polar covalent", "nonpolar covalent", or "ionic", this is often a relative term, with one molecule simply being more polar or more nonpolar than another. However, the following properties are typical of such molecules. A molecule is composed of one or more chemical bonds between molecular orbitals of different atoms. A molecule may be polar either as a result of polar bonds due to differences in electronegativity as described above, or as a result of an asymmetric arrangement of nonpolar covalent bonds and non-bonding pairs of electrons known as a full molecular orbital. Polar molecules[edit] The water molecule is made up of oxygen and hydrogen, with respective electronegativities of 3.44 and 2.20. The dipoles from each of the two bonds (red arrows) add together to make the overall molecule polar. A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole. Due to the polar nature of the water molecule itself, polar molecules are generally able to dissolve in water. Other examples include sugars (like sucrose), which have many polar oxygen–hydrogen (−OH) groups and are overall highly polar. If the bond dipole moments of the molecule do not cancel, the molecule is polar. For example, the water molecule (H2O) contains two polar O−H bonds in a bent (nonlinear) geometry. The bond dipole moments do not cancel, so that the molecule forms a molecular dipole with its negative pole at the oxygen and its positive pole midway between the two hydrogen atoms. In the figure each bond joins the central O atom with a negative charge (red) to an H atom with a positive charge (blue). The hydrogen fluoride, HF, molecule is polar by virtue of polar covalent bonds – in the covalent bond electrons are displaced toward the more electronegative fluorine atom. Ammonia, NH3, molecule the three N−H bonds have only a slight polarity (toward the more electronegative nitrogen atom). The molecule has two lone electrons in an orbital, that points towards the fourth apex of the approximate tetrahedron, (VSEPR). This orbital is not participating in covalent bonding; it is electron-rich, which results in a powerful dipole across the whole ammonia molecule. Resonance Lewis structures of the ozone molecule In ozone (O3) molecules, the two O−O bonds are nonpolar (there is no electronegativity difference between atoms of the same element). However, the distribution of other electrons is uneven – since the central atom has to share electrons with two other atoms, but each of the outer atoms has to share electrons with only one other atom, the central atom is more deprived of electrons than the others (the central atom has a formal charge of +1, while the outer atoms each have a formal charge of −​1⁄2). Since the molecule has a bent geometry, the result is a dipole across the whole ozone molecule. When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also known as the H-bond. For example, water forms H-bonds and has a molar mass M = 18 and a boiling point of +100 °C, compared to nonpolar methane with M = 16 and a boiling point of –161 °C. Nonpolar molecules[edit] A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. Not every molecule with polar bonds is a polar molecule. Carbon dioxide (CO2) has two polar C=O bonds, but the geometry of CO2 is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.

Understanding the polarity of a molecule is critical to understanding how that molecule interacts with its surroundings. But to understand polarity, one must first understand how the bonds and geometry affect each other. It's a little tricky, but worth your time.

If the bond angle is set to 180º, even if the bonds are polar, the whole molecule will still be non-polar. But the shape of water molecule is BENT with an angle of about 105°, so that's why the forces are distributed unequally and the forces cannot cancel out ******** (Please note that this video is created to help you visualize the concept of why water is a polar molecule. It does not represent how electrons actually travel - please read Heisenberg's Uncertainty Theory. Also, the shape of a water molecule is a tetrahedral geometry and you have to visualize in 3d how the bonds are formed. Last of all, an electron could be thought of as a wave. So, instead of thinking of an electron as a little orange dot, think of it as a force spreading over a volume, taking the shape of the orbital of its energy level.) Why is water a polar molecule? Water is a polar molecule because one side is positively charged and one side is negatively charged. Oxygen has 6 valence electrons and hydrogen has 1. Oxygen combines with 2 hydrogens in order to make 1 water molecule. Thus, oxygen would have 8 valence electrons as a result of the bonding and hydrogen would have 2. The water molecule fulfills the octet rule. However, oxygen attracts electrons more strongly than hydrogen. This causes the electrons to move closer to oxygen. Because of this, the oxygen ends up having a slightly negative charge and the hydrogen atom ends up with a slightly positive charge. A water molecular has a polar covalent bond. This is called a separation of charges, one end of the molecule is slightly negatively charged and the other end is slightly positively charged. Polarity means having electricity charge and that's why the water molecular is said to be a polar molecule.

01:31
If you look at the Lewis structure for H2O we can see that it is not a symmetrical molecule. However, to determine if H2O is polar we need to look at the molecular geometry or shape of the molecule. Polarity results from an unequal sharing of valence electrons. Because the H2O molecule is not symmetrical there is a region of unequal sharing. The Nitrogen atom is more electronegative and therefore the valence electrons are near them more often. This makes it more negative. The Hydrogen atoms at the bottom of the structure are then more positive. Therefore, H2O is a polar molecule.

How Does Water Bond - Covalent Bonds | Chemistry for All | FuseSchool
 
02:40
Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
 
09:46
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

Is SO3 Polar or Nonpolar
 
01:07
If you look at the Lewis structure for SO3 it appears to be a symmetrical molecule. However, to determine if SO3 is polar we need to look at the molecular geometry or shape of the molecule. Polarity results from an unequal sharing of valence electrons. In SO3 there is the sharing is equal. Therefore SO3 is a nonpolar molecule. Note, a small error. The lewis structure shows the bottom oxygen having a double bond and three lone pairs. This is not correct, it should only have two lone pairs. It doesn't change the polarity of SO3, but it's always good to be 100% accurate. SO3 Lewis Structure Explanation: http://www.youtube.com/watch?v=a-ppp5_qhZY

Hydrogen Bonds - What Are Hydrogen Bonds - How Do Hydrogen Bonds Form
 
02:48
In this video we discuss hydrogen bonds. We cover how do hydrogen bonds form, the different elements that take part in hydrogen bonds, and why doesn't oil and water mix. What are hydrogen bonds? An attractive force called a hydrogen bond can exist between certain molecules. These bonds are weaker than ionic or covalent bonds, because it takes less energy to break these types of bonds, however, a large number of these bonds going on can exert a strong force. Hydrogen bonds are the result of an unequal charge distribution on a molecule, these molecules are said to be polar. If we look at a water molecule, we can see the oxygen atom shares electrons with 2 different hydrogen atoms. So, in total this molecule has 10 protons, 8 from oxygen and 1 each from the hydrogen atoms, and a total of 10 electrons, 2 shared between the oxygen atom and hydrogen atom number one, 2 shared between the oxygen atom and hydrogen atom number 2, and the other 6 non shared electrons from the oxygen atom. So, this water molecule is electrically neutral, but it has a partial positive side, the hydrogen side, and a partial negative side, the oxygen side of the molecule. The electrons are not shared equally within the molecule, as they have a higher probability of being found closer to the nucleus of the oxygen atom, giving that end a slightly negative charge. So, the hydrogen atoms end of the molecule will have a slightly positive charge. These charged ends weakly attach the positive end of one water molecule to the negative end of an adjacent water molecule. When water is in liquid form there a few hydrogen bonds, solid form, many bonds, and when water is steam or gas, there are no bonds, because the molecules are too far apart to form any bonds. Hydrogen bonds only form between hydrogen atoms that are covalently bonded, or bonds where electrons are being shared and not transferred, to an oxygen, nitrogen or fluorine atom. These bonds make water ideal for the chemistry of life. Hydrogen bonds are also important in the structure of proteins and nucleic acids, which we will cover in later videos. So, now we know that water molecules are polar, or have slightly positive and slightly negative ends, and in fact, many lipids, or fats and oils, are not polar. So their molecules share electrons equally in their bonds. So, these are nonpolar molecules. This means that when water and oil come together they do not form bonds with one another. Even when we try to mix them, the water molecules will eventually separate because their polar molecules are attracted to one another and will form hydrogen bonds, separating the water and the nonpolar oil molecules.

Is OF2 Polar or Nonpolar? (Oxygen Difluoride)
 
02:18
Learn to determine if OF2 is polar or non-polar based on the Lewis Structure and the molecular geometry (shape). We start with the Lewis Structure and use VSEPR to determine the shape of the molecule. After that we’ll look at how the shape of the molecule, based on VSEPR, allows us to determine if the entire molecule is polar or nonpolar. If you look at the Lewis structure for OF2 it does not appear a symmetrical molecule. However, to determine if OF2 is polar we must consider the molecular geometry. A polar molecule results from an unequal/unsymmetrical sharing of valence electrons. In OF2 the sharing is not equal and there is a net dipole. Therefore, OF2- is a polar molecule.

Polar Covalent, Nonpolar Covalent and Ionic Bonds - This is a quick video describing the differences between Ionic Bonds and Covalent bonds (Polar Covalent Bonds and Nonpolar Covalent Bonds). This video demonstrates how these bonds can be classified based on electronegativity. This video also defines what a polar bond is, relative to an ionic bond. Bond polarity is a difficult topic, so I try extra hard to make it clear. I really think you can watch the video, then totally understand the topic. I have another video which explains the polarity of molecules. Molecular polarity depends on bond polarity to a certain degree. Check it out if you like this video.

Is NH3 Polar or Nonpolar? (Ammonia)
 
01:19
If you look at the Lewis structure for NH3 we can see that it is not a symmetrical molecule. However, to determine if NH3 is polar we need to look at the molecular geometry or shape of the molecule. Polarity results from an unequal sharing of valence electrons. Because the NH3 molecule is not symmetrical there is a region of unequal sharing. The Nitrogen atom is more electronegative and therefore the valence electrons are near them more often. This makes it more negative. The Hydrogen atoms at the bottom of the structure are then more positive. Therefore, NH3 is a polar molecule.

I give just a brief look into the difference of a non-polar and polar covalent bonds. I also use an example for each. Do realize that I did not name off electron negativity values for every element but I do for the ones that I use. Also in the end I should had said a negative partial charge on oxygen and a partial positive charge on the hydrogen.
