Vedclass · Answer

(D) The reaction involves an intramolecular esterification (lactonization) between the carboxylic acid group $(-COOH)$ and the hydroxymethyl group $(-CH_2OH)$ in the presence of an acid catalyst $(HCl_{(g)})$. $1$. The carboxylic acid group is protonated by $HCl$,making the carbonyl carbon more electrophilic. $2$. The oxygen atom of the $-CH_2OH$ group acts as a nucleophile and attacks the activated carbonyl carbon. $3$. This leads to the formation of a cyclic ester (lactone). $4$. Water is eliminated in the process to form the final lactone product. The structure shown in option $D$ represents the correct cyclic lactone formed by the reaction of the carboxylic acid and the hydroxymethyl group.

The major product expected from the following reaction is:
$2-(\text{carbamoyl})-3-(\text{hydroxymethyl})-6-(\text{hydroxy})\text{benzoic acid} \xrightarrow{HCl_{(g)} / CCl_4} ?$
