    A fruity smell is produced by the reaction of \[{{C}_{2}}{{H}_{2}}OH\]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 :

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