    In the reaction \[\underset{C{{H}_{2}}OH}{\overset{C{{H}_{2}}OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,HOH\,}}}\,+\underset{COOH}{\overset{COOH}{\mathop{|\ \ \ \ \ \ \ \ }}}\,\xrightarrow{110{}^\circ C}(A)\] product A will be               [Pb . CET 2001]

    A)                 Glycerol monoformate

    B)                 Allyl alcohol

    C)                 Formaldehyde

    D)                 Acetic acid

    Correct Answer: A

    Solution :

               \[\underset{\text{Glycerol}}{\mathop{\underset{C{{H}_{2}}OH}{\overset{C{{H}_{2}}OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,HOH\ \ }}}\,}}\,+\underset{\text{oxalic acid}}{\mathop{\underset{COOH}{\overset{COOH}{\mathop{|\ \ \ \ \ \ \ \ \ \ }}}\,}}\,\xrightarrow{110{}^\circ C}\underset{\text{Glycerol acid oxalate}}{\mathop{\underset{C{{H}_{2}}OH\ \ \ \ \ \ \ \ \ \ \ \ \ \ }{\overset{C{{H}_{2}}-O-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,HOH\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }}}\,}}\,\]                                                 \[\xrightarrow{-C{{O}_{2}}}\underset{\text{Glycerol monoformate}}{\mathop{\underset{C{{H}_{2}}OH\ \ \ \ \ \ \ \ \,}{\overset{C{{H}_{2}}-O-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,HOH\ \ \ \ \ \ \ \ \ \ }}}\,}}\,\]
