Enol Content || Its Comparison

The process whereby a hydrogen atom attached to the alpha-carbon of carbonyl compound moves to the carbonyl oxygen atom is known as enolization or keto-enol tautomerism. Isomeric carbonyl and enol structure are tautomers. ltbgt Normally, the carbonyl form is favoured but structure factor marked affect K_(T) . Which of the following compounds will not exhibit enozation?

Keto enol tautomerism is not observed in:
