Vedclass · Answer

(A) Tautomerism requires the presence of an $\alpha$-hydrogen atom adjacent to a carbonyl group. Compounds with an active methylene group $(-CH_2-)$ flanked by two electron-withdrawing carbonyl groups (like in $\beta$-keto esters) undergo tautomerization most readily due to the stabilization of the resulting enol form by resonance and intramolecular hydrogen bonding. In $CH_3COCH_2CO_2C_2H_5$ (ethyl acetoacetate),the methylene group is between two carbonyl groups,making it highly acidic and prone to tautomerization. Therefore,the correct option is $A$.
