(a)
Interpretation:
To identify which compound is more acidic in a given set of compounds.
Concept introduction:
Keto-enol isomerization is possible when a keto group present in the compound has a movable hydrogen atom in the next carbon attached to the carbonyl group. This occurs generally in almost all keto compounds where a chemical equilibria is present between the keto and enol form of the compound. Conversion of keto to its enol form is known as keto-enol tautomerisation. If the formed enolate (conjugate base) is stabilized by delocalization of the charge and if the hydrogen that is going to be removed are surrounded by more electron withdrawing groups then that compound is said to be more acidic.
To Find : To find which compound is more acidic
