GENERAL CHEMISTRY PAGE 21 OF 22 CCl 4 µ = 0.0 D C Cl Cl Cl Cl Examples : Determining Whether a Molecule is Polar or Non-polar A dipole = material with positively and negatively charged ends Polar bonds or molecules have one end slightly positive, δ + , and the other slightly negative, δ + Dipole moment, µ is a measure of the size of the polarity Measured in debyes, D For a molecule to be polar: It must have polar bonds based on electronegativity difference Have an unsymmetrical shape
