    A fruity smell is obtained by the reaction of ethanol with

    A) \[~C{{H}_{3}}COC{{H}_{3}}~~~~~~~\]   

    B)  \[PC{{l}_{5}}\]

    C)  \[C{{H}_{3}}COOH\]

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

    Correct Answer: C

    Solution :

    \[\underset{ROH}{\mathop{Alcohol}}\,+\underset{RCOOH}{\mathop{acid}}\,\underset{(RCOOR)}{\mathop{ester}}\,\](fruity smelling) alcohol \[({{C}_{2}}{{H}_{5}}OH)\] when react with acid they produce ester and esters have fruity smell. \[\underset{\text{Ethyl}\,\text{alcohol}}{\mathop{{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}}}\,\,+\,\underset{\text{Acetic}\,\text{acid}}{\mathop{C{{H}_{3}}COOH}}\,\xrightarrow{{}}\underset{\text{Fruity}\,\text{smell}\,\text{of}\,\text{ester}}{\mathop{{{C}_{2}}{{H}_{5}}COOC{{H}_{3}}}}\,+{{H}_{2}}O\]
