$Ph-C(=O)-^{18}O-C_2H_5$

Vedclass · Answer

(D) In the Fischer esterification reaction between a carboxylic acid and an alcohol,the $OH$ group is removed from the carboxylic acid and the $H$ atom is removed from the alcohol to form water $(H_2O)$.Therefore,the oxygen atom from the alcohol $(^{18}O)$ is incorporated into the ester linkage.The reaction is: $Ph-COOH + C_2H_5-^{18}OH \xrightarrow{H^+} Ph-C(=O)-^{18}O-C_2H_5 + H_2O$.Thus,the correct option is $D$.
