Q18 / 160 · AP EAMCET 2018 (22 Apr Shift 2) · Chemistry

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

Correct answer
A
Prop-2-enoic acid
B
2-butene
C
2-methyl-2-butenoic acid
D
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.

Hence, the correct answer is option: 'A'.
