Vedclass · Answer

(D) The alkaline hydrolysis of esters follows a nucleophilic acyl substitution mechanism. The rate of this reaction depends on the electrophilicity of the carbonyl carbon. Electron-withdrawing groups $(EWG)$ increase the electrophilicity of the carbonyl carbon by pulling electron density away from it,thereby facilitating the attack of the nucleophile $(OH^-)$. Among the given substituents,the nitro group $(-NO_2)$ is the strongest electron-withdrawing group due to its strong $-I$ and $-M$ effects. Therefore,p-nitro phenyl acetate will be hydrolysed most easily.

Compound	Reaction with $Na$ metal	Reaction with $NaOH$	Reaction with $NaHCO_3$
Alcohol	$H_2$ is liberated	No reaction	No reaction
Phenol	$H_2$ is liberated	Soluble salt formed	No reaction
Carboxylic acid	$H_2$ is liberated	Soluble salt formed	$CO_2$ gas is liberated

Which one of the following esters gets hydrolysed most easily under alkaline conditions?
