    Mesooxalic acid is formed when glycerol reacts with:

    A)  \[KMn{{O}_{4}}\]

    B)  \[Bi{{(N{{O}_{3}})}_{2}}\]

    C)  dil \[HN{{O}_{3}}\]

    D)  \[{{H}_{2}}{{O}_{2}}+FeS{{O}_{4}}\]

    Correct Answer: B

    Solution :

     \[\underset{Glycerol}{\mathop{\underset{\begin{smallmatrix}  | \\  C{{H}_{2}}OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{2}}OH \\  | \end{smallmatrix}}{\mathop{CHOH}}}\,}}\,\xrightarrow[{}]{{}}\underset{Oxalic\text{ }add}{\mathop{\underset{\begin{smallmatrix}  | \\  COOHMeso \end{smallmatrix}}{\overset{\begin{smallmatrix}  COOH \\  | \end{smallmatrix}}{\mathop{CO}}}\,}}\,\] Thus glycerol is oxidised by\[Bi{{(N{{O}_{3}})}_{2}}\]to produce mesb-oxalic acid.
