Question

Which of the following compound can show both optical and geometrical isomerism?

• A.
• B.
• C.
• D. Both (a) and (c)

Answer 1

The correct option is D Both (a) and (c)

Compound (b) does not show optical isomerism due to the presence of plane of symmetry about the plane of paper.

Compound (a) and (c) can show geometrical isomerism due to the presence of two methyl groups in ring. They also show optical isomerism due to the lack of symmetry in the molecules.

Hence, option (d) is correct.
