Isomerism

Question

Complexes exhibit isomerism.Presence of the following ligand is a necessary condition to exhibit linkage isomerism by a complex

Moderate

A

${SO}_{4}^{- 2}$
B

${NO}_{2}^{-}$
C

$C_{2} O_{4}^{- 2}$
D

$H_{2} N - {CH}_{2} - {CH}_{2} - {NH}_{2}$

Solution

${CN}^{-}, {SCN}^{-}, {NO}_{2}^{-}, {ONO}^{-}, {NC}^{-}, {NCS}^{-}$ are ambidendate ligands. Complexes containing ambidentate ligands exhibit linkage isomerism.
$Ex : - {[Co {({NH}_{3})}_{5} {NO}_{2}]}^{+ 2} and {[Co {({NH}_{3})}_{5} ONO]}^{+ 2}$
