                    Benzoic acid may be converted to ethyl benzoate by reaction with:                        

    A)                         sodium ethoxide

    B)                 ethyl chloride

    C)                 dry \[HCl-{{C}_{2}}{{H}_{5}}OH\]

    D)                 ethanol

    Correct Answer: C

    Solution :

                    Ethyl benzoate is prepared by reacting benzoic acid and ethanol in presence of dry HCl. This reaction is known as esterification reaction.                 \[\begin{align}   & \underset{Benzoic\,acid}{\mathop{{{C}_{6}}{{H}_{5}}COOH}}\,+\underset{Ethanol}{\mathop{{{C}_{2}}{{H}_{5}}OH}}\,\underset{Dry}{\mathop{\xrightarrow{HCl}}}\, \\  & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underset{Ethyl\,\,benzoate}{\mathop{{{C}_{6}}{{H}_{5}}COO{{C}_{2}}{{H}_{5}}+{{H}_{2}}O}}\, \\ \end{align}\]
