 [Co (NH3)4 (NO 2)2]CI exhibit its: [AIPMT (S) 2006]

A) linkage isomerism, ionization isomerism and optical isomerism

B) linkage isomerism, ionization isomerism and geometrical isomerism

C) ionization isomerism, geometrical isomerism and optical isomerism

D) linkage isomerism, geometrical isomerism and optical isomerism

Correct Answer: B

Solution :

[b] The compound [Co(NH3)4 (NO2)2]Cl exhibits linkage, ionisation and geometrical isomerism. Hence, its linkage isomers are

(i) [Co(NH3)4(NO2)2]Cl

and       [Co(NH3)4(ONO)2] Cl

(ii) its ionisation isomers are

[Co (NH3)4 (NO2) Cl] NO2

and       [Co (NH3)4 (NO2)2] CI

(iii)        its geometrical isomers are
