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

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