Coordination Compounds

Question
CBSEENCH12011285
Wired Faculty App

The existence of two different coloured complexes with the composition of [Co(NH3)4Cl2]+ is due to 

  • linkage isomerism

  • geometrical isomerism

  • Coordination isomerism

  • Ionisation isomerism

Solution

B.

geometrical isomerism

Complexes of [MA4B2] type exhibit geometrical isomerism.
The complex [Co(NH3)4Cl2]+ is a [MA4B2] type complex and thus, fulfils the conditions that are necessary to exhibit geometrical isomerism. Hence, it has two geometrical isomers
