The reaction of acetone with\[PC{{l}_{5}}\]gives

A) \[C{{H}_{3}}COC{{H}_{2}}Cl\]    

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

C)                  

D) \[ClC{{H}_{2}}COC{{H}_{2}}Cl\]

Correct Answer: C

Solution :

                 Acetone reacts with\[PC{{l}_{5}}\]to give 2, 2-dichloropropane. \[\underset{2,\text{ }2-dichloropropane}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}}}\,+POC{{l}_{3}}\]
