    \[C\xrightarrow[{}]{{{H}_{2}}O}D\] Here, D is

    A)  \[C{{H}_{3}}\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\mathop{CH}}\,OC{{H}_{2}}C{{H}_{3}}\]

    B)  \[C{{H}_{3}}O\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\mathop{CH}}\,C{{H}_{2}}C{{H}_{3}}\]

    C)  \[C{{H}_{3}}\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\mathop{CH}}\,C{{H}_{2}}C{{H}_{2}}OH\]

    D)  \[C{{H}_{3}}C{{H}_{2}}\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\mathop{CH}}\,C{{H}_{2}}OH\]

    Correct Answer: C

    Solution :

     \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}\xrightarrow[-{{H}_{3}}P{{O}_{3}}]{PB{{r}_{3}}}\underset{(A)}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Br \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}}}\,\]
