As in Chemistry, the two main classes of molecules are divided into polar molecules and non-polar molecules. Formula: The chemical formula of iodine is I2. To determine the polarity of a covalent bond using numerical means, the difference between the electronegativity of the atoms is used. Due to the simple nonpolar nature of Ethylene, the structure has a melting point of -169˚C and a boiling point of -104˚C. A molecule in which the bond dipoles present do not cancel each other out and thus results in a molecular dipole. The three chloride atoms have a negative charge, and the one boron in the center has an equal but positive charge. The terms "polar" and "nonpolar" are usually applied to covalent bonds, that is, bonds where the polarity is not complete. When it comes to the polarity of a molecule, a simple question that strikes our mind considering BrF5 or (Bromine Pentafluoride as it is popularly known), is whether it’s a polar or non-polar molecule? Polar compounds have a net dipole due to polar bonds that are arranged asymmetrically. Some molecules are certainly polar or nonpolar, while many have some polarity and fall someplace in between. It is a type of bond that occurs when two atoms share a pair of electrons with each other. Strongly polar compounds like sugars (e.g. Charges: It results in the formation of opposite partial charges on the bonded atoms which is called dipole.
