Identify the compound that exhibits tautomerism-

A

lactic acid

B

2 - pentanone

C

phenol

D

2 - butene

Text Solution

Verified by Experts

The correct Answer is:
B
In 2 - pentanone, `alpha - H` is present with respect to the funcitonal group
.
As a result, 2 - pentanone exhibits keto - enol tautomerism. On the other hand, phenol (an enol) does not maintain any equilibrium with the form because phenol has aromatic stabliisation.
