\[C{{H}_{3}}COCl\]does not react with:

A)  diethyl ether   

B)  phenol

C)   ethanol                             

D)   aniline

Correct Answer: B

Solution :

\[\underset{diethyl\,\,ether}{\mathop{{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}}}\,+C{{H}_{3}}\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,Cl\xrightarrow{ZnC{{l}_{2}}}\]\[{{C}_{2}}{{H}_{5}}Cl+C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}\] \[C{{H}_{3}}CO\underset{ethanol}{\mathop{O{{C}_{2}}{{H}_{5}}}}\,\xrightarrow{{}}\]\[C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}+HCl\] Acetyl chloride does not react direct with phenol. Firstly phenol reacts with alkali to form sodium phenoxide which reacts with acetyl chloride to give phenyl acetate.
