Which one of the following comppunds will not show geomtricalisomerism?

Options

A. Pro -2-enoic acid
B. 2- butene
C. 2-methyl-2-butenoic acid
D. 3-methyl -2-pentenoic acid

Answer

A

Explanation

Prop -2-enoic acid will not show goemetrical isomerism . Geomaterical isomerse occur where we have restricted rotation somewhere in a molecules , between carbon atoms like but -2- ene.

Prop -2- eneonic acid deos not show geomaterically isomerism.
