Vedclass · Answer

(D) The reaction proceeds as follows:$1$. $CH_3-COOH \xrightarrow{LiAlH_4} CH_3-CH_2-OH$ (Reduction of carboxylic acid to primary alcohol).$2$. $CH_3-CH_2-OH \xrightarrow{PCC} CH_3-CHO$ (Oxidation of primary alcohol to aldehyde).$3$. $CH_3-CHO \xrightarrow{HCN/OH^-} CH_3-CH(OH)-CN$ (Nucleophilic addition of $HCN$ to aldehyde to form cyanohydrin).$4$. $CH_3-CH(OH)-CN \xrightarrow{H_2O/OH^-, \Delta} CH_3-CH(OH)-COOH$ (Hydrolysis of nitrile group to carboxylic acid).Thus,the final product $P$ is $CH_3-CH(OH)-COOH$.
