    In the reaction \[C{{H}_{3}}C{{H}_{2}}COOH\xrightarrow{C{{l}_{2}},\,\,P}X\xrightarrow{alc.\,\,KOH}Y,\,\,Y\]is

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

    B)        \[C{{H}_{2}}=CHCOOH\]

    C)        \[C{{H}_{3}}C{{H}_{2}}CN\]

    D)        \[\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{C}}\,{{H}_{2}}C=COOH\]

    Correct Answer: B

    Solution :

    \[C{{H}_{3}}C{{H}_{2}}COOH\xrightarrow{Cl,\,\,P}C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{C}}\,H-COOH\]                 \[\xrightarrow{Alc.\,\,KOH}C{{H}_{2}}=CH-COOH\]
