4.Chemical Bonding and Molecular Structure
medium
Which amongst the following is incorrect statement?
A
$C _{2}$ molecule has four electrons in its two degenerate $\pi$ molecular orbitals.
B
$H _{2}^{+}$ion has one electron.
C
$O _{2}^{+}$ion is diamagnetic.
D
The bond orders of $O _{2}^{+}, O _{2}, O _{2}^{-}$and $O _{2}^{2-}$ are $2.5, 2, 1.5$ and $1,$ respectively.
(NEET-2022)
Solution
$O _{2}^{+}$ion is having $15$ electrons, so it contain one unpaired electron. Hence it is paramagnetic in nature.
