    An organic compound,\[{{C}_{3}}{{H}_{6}}O\]does not give a precipitate with 2, 4-dinitrophenyl hydrazine reagent and does not react with metallic sodium. It could be

    A)  \[C{{H}_{3}}C{{H}_{2}}CHO\]

    B)  \[C{{H}_{2}}=CHC{{H}_{2}}OH\]

    C)  \[C{{H}_{3}}COC{{H}_{3}}\]

    D)  \[C{{H}_{2}}CHOC{{H}_{3}}\]

    Correct Answer: D

    Solution :

     Since, the compound does not give a precipitate with 2, 4-dinitrophenylhydrazine, it cannot be an aldehyde or a ketone. Further since it does not react with metallic sodium, therefore, it cannot be an alcohol. Thus, the compound\[{{C}_{3}}{{H}_{6}}O\]must be an ether ie, option  is correct.
