    Oxalic acid when heated with concentrated \[{{H}_{2}}S{{O}_{4}}\]gives

    A) \[C{{O}_{2}}+{{H}_{2}}O\]        

    B)      \[CO+C{{O}_{2}}+{{H}_{2}}O\]                       

    C)  CO only         

    D)      \[C{{O}_{2}}\]only                          

    Correct Answer: B

    Solution :

    \[\underset{COOH}{\mathop{\underset{|}{\mathop{COOH}}\,}}\,+{{H}_{2}}S{{O}_{4}}\xrightarrow{\Delta }C{{O}_{2}}+CO+{{H}_{2}}O\] Here, \[{{H}_{2}}S{{O}_{4}}\]is a dehydrating agent. Hence, the correct option is (b).
