Vedclass · Answer

(A) The acidity of hydrogen atoms depends on the stability of the conjugate base formed after the removal of the proton. $1$. The hydrogen at position $2$ is an active methylene group flanked by two carbonyl groups (a ketone and an ester). The resulting carbanion is highly stabilized by resonance with both carbonyl groups,making it the most acidic. $2$. The hydrogen at position $1$ is an $\alpha$-hydrogen to a single carbonyl group (ketone). The resulting carbanion is stabilized by resonance with one carbonyl group,making it less acidic than position $2$. $3$. The hydrogen at position $3$ is attached to an alkyl group (specifically the ethyl group of the ester). There is no resonance stabilization for the resulting carbanion,making it the least acidic. Therefore,the order of acidity is $2 > 1 > 3$.

Consider the hydrogen atoms attached to three different carbon atoms (labeled $1$,$2$ & $3$). Rank the attached hydrogen atoms in order from most acidic to least acidic.
