    Acetic anhydride reacts with diethyl ether in the presence of anhydrous \[AlC{{l}_{3}}\] to give

    A) \[C{{H}_{3}}C{{H}_{2}}COOH\]

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

    C)  \[C{{H}_{3}}COOC{{H}_{3}}\]

    D) \[C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}\]

    Correct Answer: D

    Solution :

    \[\underset{diethyl\,\,ether}{\mathop{{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}}}\,+\underset{acetic\,\,anhydride}{\mathop{{{(C{{H}_{2}}CO)}_{2}}O}}\,\]\[\xrightarrow{AlC{{l}_{3}}}\underset{ethyl\,\,acetate}{\mathop{C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}}}\,\]
