Chapter 6, Problem 5P

Compare the electron density in the $1{\sigma }_g$ and $1{\sigma }_u^{*}$ molecular orbitals for ${\text{H}}_{\text{2}}^{\text{+}}$ shown in Figure 6.5 with the classical model for bonding for ${\text{H}}_{\text{2}}^{\text{+}}$ summarized in Figure 3.22b. Which of these molecular orbitals describes the bond in ${\text{H}}_{\text{2}}^{\text{+}}$ ?
