Molecular Polarity dipole moment **General Rule of Thumb…does the central atom contain a lone pair of electrons Some exceptions. – Example Problems: write Lewis structures; determine the molecular shape; determine polarity of molecule; determine the bond angles; and predict the hybridization. (a) CCl4 (b) BH3 (c) PF5 (why can’t NF5 exist?) (d) BeCl2 (e) NH3 (f) SF6 (g) SO2
