  • question_answer
    Acetic anhydride is obtained from acetyl chloride by the reaction of                                        [CPMT 1985, 93]

    A)                 \[{{P}_{2}}{{O}_{5}}\]    

    B)                 \[{{H}_{2}}S{{O}_{4}}\]

    C)                 \[C{{H}_{3}}COONa\]    

    D)                 \[C{{H}_{3}}COOH\]

    Correct Answer: C

    Solution :

     \[C{{H}_{3}}-COO\underline{Na}+C{{H}_{3}}-CO-\underline{Cl}\to \underset{\text{Acetic anhydride}}{\mathop{C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-O-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-C{{H}_{3}}}}\,+NaCl\]
