Geometrical isomerism is possible in case of:

A)  2-butyne       

B)         1-butene

C)  propene            

D)         2-butene

E)  pentene

Correct Answer: D

Solution :

A compound containing a double bond can show geometrical isomerism only when identical groups are not present on the double bonded carbon atom hence, 2-butene \[(C{{H}_{3}}CH=CHC{{H}_{3}})\]shows   geometrical isomerism.
