Question

According to Molecular Orbital Theory,

• A. $C _{2}^{2-}$ is expected to be diamagnetic
• B. $O _{2}^{2+}$ is expected to have a longer bond length than $O _{2}$
• C. $N _{2}^{+}$and $N _{2}^{-}$have the same bond order
• D. $He _{2}^{+}$has the same energy as two isolated He atoms

Answer 1

Answer: (A), (C)

$\rightarrow C _{2}^{2-}$ has $14 e ^{-}$. It is expected to be diamagnetic
$\rightarrow N _{2}^{+}$and $N _{2}^{-}$have the same bond order $2.5$.
