The correct statement with regard to `H_2^(+)` and `H_2^(-)` is

Options

A. Both `H_2^(+)` and `H_2^(-)` are equally stable
B. Both `H_2^+` and `H_2^(-)` do not exist
C. `H_2^(-)` is more stable than `H_2^(+)`
D. `H_2^+` is more stable than `H_2^(-)`

Answer

D

Explanation

`H_2^(+)` is more stable than `H_2^(-)` even though the bond order is the same in both the cases. This is because of the fact that presence of antibonding electron in `H_2^(-)` lowers it stability as compared to `H_2^(+)`.
