    \[X\xrightarrow{PC{{l}_{5}}}{{C}_{2}}{{H}_{5}}Cl,Y\xrightarrow{PC{{l}_{5}}}C{{H}_{3}}COCl\] X and Y are

    A)  \[{{({{C}_{2}}{{H}_{5}})}_{2}}O\]and \[C{{H}_{3}}C{{O}_{2}}H\]

    B)                  \[{{C}_{2}}{{H}_{5}}I\]and \[{{C}_{2}}{{H}_{5}}CHO\]

    C)  \[{{C}_{2}}{{H}_{5}}OH\]and \[C{{H}_{3}}C{{O}_{2}}H\]

    D)  \[{{C}_{2}}{{H}_{5}}OH\]and \[{{C}_{2}}{{H}_{5}}CHO\]

    Correct Answer: C

    Solution :

                     \[{{C}_{2}}{{H}_{5}}OH\xrightarrow{PC{{l}_{5}}}{{C}_{2}}{{H}_{5}}Cl+POC{{l}_{3}}+HCl\]\[C{{H}_{3}}C{{O}_{2}}H\xrightarrow{PC{{l}_{5}}}C{{H}_{3}}COCl+POC{{l}_{3}}+HCl\]
