Using molecular orbital theory predict the correct decreasing bond order of the following species
$1 . O_{2}^{+}$ $2 . O_{2}^{-}$ $3 . O_{2}^{2 -}$ $4 . O_{2}^{2 +}$

Options:

Answer:

Solution:

Bond order $= \frac{no.of bonding \bar{e} - no. of anti bonding \bar{e}}{2}$
Bond orders of $O_{2}^{+}, O_{2}^{-}, O_{2}^{2 -} and O_{2}^{2 +}$ are respectively 2.5, 1.5, 1 and 3
Hence $O_{2}^{2 +}$ has max bond order is
$O_{2}^{2 +} > O_{2}^{+} > O_{2}^{-} > O_{2}^{2 -}$
