Part II Interactions of Atoms: Dipoles, Polarity and Phase Changes Polar and Nonpolar Covalent Bonds polarity in molecules the existence and separation of positive and negative ends occurs when electrons are shared unequally due to differences in electronegativity ( EN) the greater the EN, the more polar the bond Relative Polarities of Hydrogen Halides The Dipole Moment: Diatomic Molecules dipole moment (μ) a measure of the polarity of a bond the greater the value of μ, the more polar the bond μ = d x q d: distance between the two charges of equal and opposite sign q: the magnitude of the charge 1 2 3 4

Molecules Polarity of Molecules molecular shape and bond polarity determine overall molecular polarity shape is predicted by VSEPR overall polarity is determined by directionality of dipoles Polarity of Molecules δ + δ - δ - vectors: equal and opposite cancel each other out net dipole moment (μ) = 0 molecule is nonpolar Polarity of Molecules δ + δ
