Q. Which of the following can participate in linkage isomerism?
A) ${NH}_{3}$
B) $H_{2}O$
C) $H_{2}{NCH}_{2}{CH}_{2}{NH}_{2}$
D) ${NO}_{2}^{-}$
Explanation
(d)
Linkage isomerism is exhibited by ambidentate ligands (ligands having two coordination sites). e.g., $NO_{2}^{-}$.
If the bonding is through N, the ligand is named as nitro and if it is through O, it is named as nitrito.
$NO_{2}^{-} \rightarrow$ nitro —N
$ONO^{-} \rightarrow$nitrito —O
