easy

According to molecular theory, the species among the following that does not exist is

A

$He _{2}^{+}$

B

$He _{2}^{-}$

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.
