    Identify the compound Z, In this reaction sequence \[C{{H}_{3}}C{{H}_{2}}COOH\xrightarrow[{}]{N{{H}_{3}}}X\xrightarrow[{}]{B{{r}_{2}}+KOH}\] \[Y\xrightarrow[{}]{HN{{O}_{2}}}Z:\]

    A) \[C{{H}_{3}}OH\]             

    B)        \[C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\]

    C) \[C{{H}_{3}}C{{H}_{2}}OH\]   

    D)        \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}OH\]

    E) \[C{{H}_{3}}N{{H}_{2}}\]

    Correct Answer: C

    Solution :

    \[\underset{propionic\text{ }acid}{\mathop{C{{H}_{3}}C{{H}_{2}}COOH}}\,\xrightarrow[{}]{N{{H}_{3}}}\underset{\begin{smallmatrix}  propionamide \\  \,\,\,\,\,\,\,\,\,\,\,\,\,(X) \end{smallmatrix}}{\mathop{C{{H}_{3}}C{{H}_{2}}CON{{H}_{2}}}}\,\] \[\xrightarrow[{}]{B{{r}_{2}}+KOH}\underset{\begin{smallmatrix}  ethyl\text{ }amine \\  \,\,\,\,\,\,\,\,\,\,\,\,\,(Y) \end{smallmatrix}}{\mathop{C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}}}\,\xrightarrow[{}]{HN{{O}_{2}}}\] \[\underset{\begin{smallmatrix}  ethyl\text{ }alcohol \\  \,\,\,\,\,\,\,\,\,\,\,(Z) \end{smallmatrix}}{\mathop{C{{H}_{3}}C{{H}_{2}}OH}}\,\]
