Vedclass · Answer

(B) The position $(X)$ corresponds to the carboxylic acid group $(-COOH)$,which is the most acidic site in the molecule.Between the two amino groups at positions $(Y)$ and $(Z)$,the position $(Y)$ is closer to the electron-withdrawing $-COOH$ group.The electron-withdrawing effect of the $-COOH$ group decreases the electron density on the nitrogen atom at position $(Y)$ more than at position $(Z)$,making the conjugate acid of $(Y)$ more stable (or the amino group at $(Y)$ less basic,which implies its conjugate acid is more acidic).Therefore,the correct order of acidity is $X > Y > Z$.

What is the correct order of acidity for the positions $(X)$,$(Y)$,and $(Z)$ in the given compound?
