    Formic acid is obtained when     [NCERT 1974]

    A)                 Calcium acetate is heated with conc. \[{{H}_{2}}S{{O}_{4}}\]

    B)                 Calcium formate is heated with calcium acetate

    C)                 Glycerol is heated with oxalic acid at \[{{110}^{o}}C\]

    D)                 Acetaldehyde is oxidised with \[{{K}_{2}}C{{r}_{2}}{{O}_{7}}\] and \[{{H}_{2}}S{{O}_{4}}\]

    Correct Answer: C

    Solution :

                    \[\begin{matrix}    COOH  \\    \overset{|}{\mathop{C}}\,OOH  \\ \end{matrix}\underset{\text{Decarboxylation}}{\mathop{\xrightarrow{\text{Glycerol,}\,110{}^\circ C}}}\,HCOOH+C{{O}_{2}}\]
