Statement I The geometrical isomers of the complex $\left[M\left(NH _3\right) _4 Cl _2\right]$ are optically inactive.
Statement II Both geometrical isomers of the complex $\left[M\left(NH _3\right) _4 Cl _2\right]$ possess axis of symmetry.
$(2008,3 M)$

Answer:
Correct Answer: 20. (b)
Solution:
- Both statements are true. However, axis of symmetry is not a criteria of optical isomerism. Optical inactivity of the two geometrical isomers of $\left[M\left(NH _3\right) _4 Cl _2\right]$ is due to the presence of plane of symmetry.
