\[[Co{{(N{{H}_{3}})}_{4}}{{(N{{O}_{2}})}_{2}}]Cl\]exhibits

A)  linkage isomerism, ionisation isomerism and optical isomerism

B)  linkage isomerism, ionisation isomerism and geometrical isomerism

C)  Ionisation    isomerism,    geometrical isomerism and optical isomerism

D)  linkage isomerism, geometrical isomerism and optical isomerism

Correct Answer: B

Solution :

 The compound\[[Co{{(N{{H}_{3}})}_{4}}(N{{O}_{2}})]Cl\]exhibits linkage, ionisation and geometrical isomerism. Its linkage isomers are (i)\[[Co{{(N{{H}_{3}})}_{4}}(N{{O}_{2}})]Cl\]and \[[Co{{(N{{H}_{3}})}_{4}}{{(ONO)}_{2}}]Cl\] (ii) its ionisation isomers are \[[Co{{(N{{H}_{3}})}_{4}}(N{{O}_{2}})Cl]N{{O}_{2}}\]and \[[Co{{(N{{H}_{3}})}_{4}}{{(N{{O}_{2}})}_{2}}]Cl\] (iii) its geometrical isomers are
