$H_a$

Vedclass · Answer

(A) The acidity of a hydrogen atom depends on the stability of the conjugate base formed after the removal of the proton.In the given structure,$H_a$ is located between two carbonyl groups (a $\beta$-dicarbonyl system).The removal of $H_a$ generates a carbanion that is stabilized by resonance with both carbonyl groups,making it an active methylene group.Therefore,$H_a$ is the most acidic hydrogen in the molecule.
