Question

The compound which shows geometrical isomerism is

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Geometrical Isomerism arises due to different arrangement atoms/groups around a system where free rotation of bonds is restricted.

Conditions for geometrical isomers:
1) Free rotation must be restricted.
2) Both the terminals must be attached with different groups.
3) Terminals must not be in perpendicular planes.
option a, b, c, violating condition 2 thus they will not show geometrical isomerism.
The carbon in (d) has two different groups. So it exhibits geometrical isomerism. hence, the correct answer is option (d).
