    A fruity smell is produced by the reaction of \[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\,\]with

    A)  \[C{{H}_{3}}COC{{H}_{3}}\]

    B)  \[C{{H}_{3}}COOH\]

    C)  \[PC{{l}_{5}}\]

    D) \[C{{H}_{3}}CHO\]

    Correct Answer: B

    Solution :

    \[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\]reacts with \[\text{C}{{\text{H}}_{\text{3}}}\text{COOH}\]and gives ethylethanoate. Which is an ester and it has fruity smell. \[{{C}_{2}}{{H}_{5}}OH+C{{H}_{3}}COOH\xrightarrow{\text{conc}\text{.}\,{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}}\] \[\underset{\begin{smallmatrix}  \,\,\,\,\,\,\,\,\,\text{Ester} \\  (Fruity\,smell) \end{smallmatrix}}{\mathop{C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}}}\,+{{H}_{2}}O\]
