Question

$[Co(NH{)}_3{)}_4(N{O}_2{)}_2]Cl$ exhibits :-

• A. Linkage isomerism, geometrical isomerism and optical isomerism
• B. Linkage isomerism, ionisation isomerism and optical isomerism
• C. Linkage isomerism, ionisation isomerism and geometrical isomerism
• D. Ionisation isomerism, geometrical isomerism and optical isomerism

Answer 1

Answer: (C)

The compound $\left[Co{\left(N{H}_3\right)}_4{\left(N{O}_2\right)}_2\right]Cl$ exhibits linkage, ionisation and geometrical isomerism. Hence,
(i) its linkage isomers are $\left[Co{\left(N{H}_3\right)}_4{\left(N{O}_2\right)}_2\right]Cl$ and $\left[Co{\left(N{H}_3\right)}_4(ONO{)}_2\right]Cl$
(ii) its ionisation isomers are
$\left[Co{\left(N{H}_3\right)}_4\left(N{O}_2\right)Cl\right]N{O}_2$ and $\left[Co{\left(N{H}_3\right)}_4{\left(N{O}_2\right)}_2\right]Cl$
(iii) its geometrical isomers are
