Arrange the following species in the decreasing order of their bond orders:
Arrange the following species in the decreasing order of their bond orders:
(I) $>$ (II) $>$ (III)
(II) $>$ (I) $>$ (III)
(II) $>$ (III) $>$ (I)
(III) $>$ (II) $>$ (I)
Solution
( The strength of bond is determined by bond order (BO).
Number of electrons in bonding molecular orbital (a) - Number of electrons in
$
\mathrm{BO}=\frac{\text { antibonding molecular orbital }(b)}{2}
