D) Acetic acid
Show Answer
Answer:
Correct Answer: A
Solution:
$ \underset{Glycerol}{\mathop{\underset{CH_2OH}{\overset{CH_2OH}{\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{CH_2OH\ \ \ \ \ \ \ \ \ \ \ \ \ \ }{\overset{CH_2-O-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}HOH\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }}}}} $
$ \xrightarrow{-CO_2}\underset{\text{Glycerol monoformate}}{\mathop{\underset{CH_2OH\ \ \ \ \ \ \ \ }{\overset{CH_2-O-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}HOH\ \ \ \ \ \ \ \ \ \ }}}}} $
