Vedclass · Answer

(B) The stability of alcohol derivatives in an aqueous base depends on their susceptibility to hydrolysis. Esters,represented by the structure $RO-CO-CH_3$,undergo base-catalyzed hydrolysis (saponification) in an aqueous base. The mechanism involves the nucleophilic attack of the $OH^-$ ion on the carbonyl carbon of the ester,followed by the elimination of the alkoxide ion $(RO^-)$,which then abstracts a proton from the resulting carboxylic acid to form an alcohol and a carboxylate ion. Other derivatives like ethers $(RO-CH_2-C_6H_5)$ and acetals/ketals $(RO-C_5H_9O)$ are generally stable in basic media.
