1.Atom hybridization changes in many chemical reactions. In each of the following reactions, determine what change, if any, occurs to the hybridization of the underlined atom.
(a) BF3 + F- → BF4-
(b)PF3 +F2 → PF5
2.Which one of the following molecules is nonpolar?
AsBr3 BrF3 PCl5 SO2F2 NOBr
3.Use molecular orbital theory to predict the following properties of the O22+ ion:
(a) electron configuration
(b) bond order
(c) magnetic character (paramagnetic or diamagnetic)
(d) whether the bond length is longer or shorter than in the O2 molecule
(e) whether the bond strength is greater or less than in the O2 molecule. Use the M.O. diagram for O2 in Figure 10.13 of Tro, Fridgen and Shaw as a starting point for this question.
