Chapter 24, Problem 57IAE

Provide a valence bond description of the bonding in the $\text{Cr}{\left({\text{NH}}_{\text{2}}\right)}_{\text{e}}{}^{+\text{2}}$ ion. According to the valence bond description, how many unpaired electrons are there in the $\text{Cr}{\left({\text{NH}}_{\text{2}}\right)}_{\text{e}}{}^{+\text{2}}$ complex? How does this prediction compare with that of crystal field theory?
