d. 
f. 
[Draw mono enol
tautomers only]
(a)
Interpretation: The enol or keto tautomer of the given compound is to be drawn.
Concept introduction: The chemical equilibrium that exists between a keto form of a compound and an enol form of the same compound is known as keto-enol tautomerism. Tautomers refer to these keto and enol forms. The keto-enol tautomerism takes place only if the acidic hydrogen is present at the
