Polar & Non-Polar Molecules: Crash Course Chemistry #23
*** 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?

Ionic Bonds, Polar Covalent Bonds, and Nonpolar Covalent Bonds
This organic chemistry video tutorial explains how to identify a bond as an ionic bond, polar covalent bond, or a nonpolar covalent bond. Ionic bonds usually consist of metals and nonmetals where as covalent bonds consists of nonmetals. In a nonpolar covalent bond, electrons are shared equally and the electronegativity difference between the two atoms is 0.4 or less. For polar covalent bonds, the electrons are shared unequally between the two atoms and the electronegativity difference is defined to be 0.5 or more.

Polar Molecules Tutorial: How to determine polarity in a molecule
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.

Molecular Shape and Polarity: How to determine whether a molecule will be polar or nonpolar
http://purplebonding.com A polar molecule is a molecule that has poles -- a positive and negative pole to be exact. To determine whether a molecule is polar, you first need to determine if the bonds between the atoms are polar. Next, you use VSEPR, valence shell electron pair repulsion theory, to predict the shape of the molecule. Some shapes will cause the dipoles to cancel out, much as in an even-sided tug-of-war. Some shapes will be asymmetrical, and the dipoles will not cancel out. These factors explain why carbon dioxide CO2 is nonpolar, whereas water H2O is. Watch the video to learn more about determining molecular polarity.

Ionic vs. Molecular
To see all my Chemistry videos, check out http://socratic.org/chemistry How can you tell the difference between compounds that are ionic and molecular (also known as covalent)? It has to do with the elements that make them up: ionic compounds are made of metals and nonmetals, and molecular (or covalent) compounds are made of nonmetals. We'll learn how they bond differently: in covalent compounds, the atoms share electrons, and in ion compounds, atoms steal electrons and then opposite charges attract. Ionic and molecular (covalent) compounds also look different at the microscopic level: covalent and molecular compounds exist in molecules, while ionic compounds are organized in lattice structures.

Is CH2Cl2 Polar or Nonpolar?   Dichloromethane
This video discusses if CH2Cl2 is polar or nonpolar. CH2Cl2 is known as dichloromethane. It has a dipole moment of 1.60D. This video also provides the lewis structure of CH2Cl2 and discusses the bond polarity of the C-H and C-Cl using electronegativity values to determine if CH2Cl2 is polar or nonpolar.
Polar and non polar substances | Solutions | Chemistry
A polar molecule is one in which the atoms are arranged such that one end of the molecule has a positive charge and the opposite end has a negative charge.In this video we see that polar substances only dissolve in polar solvents and non polar substances in non polar solvents. Potassium permanganate, a polar compound, is added to water, a polar solvent and to carbon tetrachloride, a non polar solvent. We see that it dissolves only in water. In a similar fashion, a non polar element iodine is added to the same two solvents. This time, we see, that iodine only dissolves in carbon tetrachloride.

Bonding: Polar Vs. Non-Polar Molecules
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.

Polar Covalent Bonds and Nonpolar Covalent bonds, Ionic Bonding - Types of Chemical Bonds
This chemistry video tutorial provides a basic introduction into the types of chemical bonds such as polar covalent bonds, nonpolar covalent bonds and ionic bonds. It discusses the difference between ionic bonding and covalent bonding. Ionic bonds can be identified by looking for a metal combined with a nonmetal. Covalent bonds typically occur among 2 or more nonmetals. Covalent bonding involves a sharing of electrons and ionic bonding forms as a result of a transfer of electrons from the metal to the nonmetal producing ions with opposite charge which are attracted to each other. The electrostatic force of attraction produces the ionic bond that holds the cations and anions together. Polar covalent bonds have unequal sharing of electrons between the atoms where as nonpolar covalent bonding have a relatively equal sharing of electrons between the atoms attached to the bond. Polar covalent bonds typically have an electronegativity difference of 0.5 or more where as nonpolar covalent bonds have a value difference of 0.4 or less. This video contains plenty of examples and practice problems.

VSEPR Theory: Introduction
To see all my Chemistry videos, check out http://socratic.org/chemistry This is an introduction to the basics of VSEPR Theory. VSEPR theory is a set of rules for how to look at a Lewis structure and determine the three dimensional (3D) shape of a molecule. The shapes have to do with the location of bonds and lone electrons pairs. In this video, we'll look at the following shapes: linear, trigonal planar, bent, tetrahedral, and trigonal bipyramidal
