The two esters below are synthesized from the starting material below. identify and draw the neutral reagent that is missing.

The two Esters along with starting materials are shown below. The missing reagents ate shown in Blue encircled in red box. First reaction is carried out in acid which increases the reactivity of carboxylic acid (electrophilicity odf carbonyl carbon). And second reaction is carried out in the presence of Base, which increases the Nucleophilicity of nucleophile i.e. Alcohols.

Ibelieve y y even though i've only taken chemistry for one year
