Which of the following coordination compounds has maximum number of isomers ?
Options
- APt NH 3 4 Cl 2 2+
- BPt gly 3 2 −
- CPt en 3 4+
- DPt NH 3 2 Cl 2
Correct answer
B. Pt gly 3 2 −
Step-by-step solution
Pt NH 3 4 Cl 2 2+ has 2 geometrical isomers. Pt gly 3 2 − will have 2 geometrical isomers, both of which will be optical active, giving a total of 4 isomers. Pt en 3 4+ will have no geometrical isomers, but the compound will be optically active, hence total two isomers. Pt NH 3 2 Cl 2 will have two geometrical isomers.
