Chapter 5, Problem 39E

Determine the bond order of each member of the following groups, and determine which member of each group is predicted by the molecular orbital model to have the strongest bond.

(a) ${\text{H}}_{\text{2}}{\text{, H}}_{\text{2}}{}^{\text{+}}{\text{, H}}_{\text{2}}{}^{\text{–}}$

(b) ${\text{O}}_{\text{2}}{\text{, O}}_{\text{2}}{}^{\text{2+}}{\text{, O}}_{\text{2}}{}^{\text{2–}}$

(c) ${\text{Li}}_{\text{2}}{\text{, Be}}_{\text{2}}{}^{\text{+}}{\text{, Be}}_{\text{2}}$

(d) ${\text{F}}_{\text{2}}{\text{, F}}_{\text{2}}{}^{\text{+}}{\text{, F}}_{\text{2}}{}^{\text{-}}$

(e) ${\text{N}}_{\text{2}}{\text{, N}}_{\text{2}}{}^{\text{+}}{\text{, N}}_{\text{2}}{}^{\text{-}}$
