    B) \[2,\,\,2\mathbf{-}\]propane diol

    C)  iso-propyl alcohol

    D)  acetaldehyde

    Correct Answer: A

    Solution :

    \[\underset{2,2-dichloro\,propane}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}}}\,\xrightarrow{Hydrolysis}\]                 \[\underset{unstable}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  OH \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}}}\,\xrightarrow[-{{H}_{2}}O]{}\]                                                 \[\underset{acetone}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}}}\,\]
