Options
- A. Pt ( en ) ( SCN ) 2
- B. Zn NH 3 2 Cl 2
- C. Pt NH 3 2 Cl 4
- D. Cr ( en ) 2 H 2 O SO 4 +
Answer
D. Cr ( en ) 2 H 2 O SO 4 +
Step-by-step solution
Pt NH 3 2 Cl 2 is a square planar complex and it can exhibit geometrical isomerism. It has two isomers, cis-platin and trans-platin. The complexes Zn NH 3 2 Cl 2   tetrahedral   and   Pt ( en ) ( SCN ) 2 does not exhibit geometrical isomerism. The octahedral complex Pt NH 3 2 Cl 4 shows geometrical isomerism, it has two geometrical isomers cis and trans. Cr ( en ) 2 H 2 O SO 4 + is an octahedral complex, it is of the type M AA 2 bc and it can exhibit the geometrical isomerism.
