A
$He _{2}^{+}$
B

C
$Be _{2}$
D
$O _{2}^{2-}$
(JEE MAIN-2021)
Solution
| Chemical Species | Bond Order |
| $He _{2}^{+}$ | $0.5$ |
| $He _{2}^{-}$ | $0.5$ |
| $Be _{2}$ | $0$ |
| $O _{2}^{2-}$ | $1$ |
According to $M.O.T.$ If bond order of chemical species is zero then that chemical species does not exist.
