    The hydrolysis product of which compound form sodium bisulphite addition product but does not give silver mirror with Tollen's reagent?

    A)  \[Cl-C{{H}_{2}}C{{H}_{2}}Cl\]  

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

    C)  \[C{{H}_{3}}C(C{{l}_{2}})C{{H}_{3}}\]   

    D)  \[C{{H}_{2}}C{{l}_{2}}\]

    Correct Answer: C

    Solution :

     \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}\xrightarrow[{}]{2{{H}_{2}}O}\left[ C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  OH \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}} \right]\] \[\xrightarrow[-{{H}_{2}}O]{Rearrangement}\underset{acetone}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}}}\,\] acetone forms sodium bisulphide addition product but does not give silver mirror with Tollen's reagent.
