Which one of the following compounds will not show geometrical isomerism?

Which one of the following compounds will not show geometrical isomerism?
  1. Prop-2-enoic acid
  2. 2-butene
  3. 2-methyl-2-butenoic acid
  4. 3-methyl-2-pentenoic acid

Solution

Prop-2-enoic acid will not show geometrical isomerism. Geometrical isomers occur where we have restricted rotation somewhere in a molecule, between carbon atoms like - but-2-ene.
Prop-2-eneonic acid does not show geometrically isomerism. ^
