The pair(s) of coordination complexes/ions exhibiting the same kind of isomerism is (are)
Options
- ACr NH 3 5 Cl Cl 2 and Cr NH 3 4 Cl 2 Cl
- BCo NH 3 4 Cl 2 + and Pt NH 3 2 H 2 O Cl +
- CCo Br 2 Cl 2 2 - and Pt Br 2 Cl 2 2 -
- DPt NH 3 3 NO 3 Cl and Pt NH 3 3 Cl Br
Correct answer
B. Co NH 3 4 Cl 2 + and Pt NH 3 2 H 2 O Cl +
Step-by-step solution
Cr NH 3 5 Cl Cl 2 and Cr NH 3 4 Cl 2 Cl , both compounds will not show either structural or stereoisomerism. Co NH 3 4 Cl 2 + and Pt NH 3 2 H 2 O Cl + , Ma 4 b 2 type (octahedral), Ma 2 bc type (square planar) and both will show geometrical isomerism. Co Br 2 Cl 2 2 - and Pt Br 2 Cl 2 2 - , Ma 4 b 2 type (tetrahedral), Ma 2 b 2 (square planar). Pt NH 3 3 NO 3 Cl and Pt NH 3 3 Cl Br both will show ionisation isomerism.
