Vedclass · Answer

(A) The starting material is salicylic acid ($2$-hydroxybenzoic acid).$1$. Reaction with '$X$' leads to the acetylation of the phenolic $-OH$ group to form aspirin (acetylsalicylic acid). The reagent used for acetylation is acetic anhydride $((CH_3CO)_2O)$ in the presence of an acid catalyst $(H^+)$.$2$. Reaction with '$Y$' leads to the esterification of the carboxylic acid $-COOH$ group to form methyl salicylate. The reagent used for esterification is methanol $(CH_3OH)$ in the presence of an acid catalyst $(H^+)$ and heat $(\Delta)$.Therefore,'$X$' is $(CH_3CO)_2O / H^{+}$ and '$Y$' is $CH_3OH / H^{+}, \Delta$.

In the given reaction,reagents '$X$' and '$Y$' respectively are:
