    A and B are the compounds of carbon. A on passing over red hot coke is converted to B. Then A and B are respectively

    A)  \[CO,C{{O}_{2}}\]                          

    B)  \[C{{O}_{2}},CO\]

    C)  \[C{{H}_{4}},{{C}_{2}}{{H}_{6}}\]                             

    D)  \[CC{{l}_{4}},CHC{{l}_{3}}\]

    Correct Answer: B

    Solution :

                     Red hot coke acts as a reducing agent and reduces \[\text{C}{{\text{O}}_{2}}\]to CO. \[\underset{A}{\mathop{C{{O}_{2}}}}\,+\underset{\text{(red}\,\text{hot)}}{\mathop{C}}\,\xrightarrow{{}}\underset{B}{\mathop{2CO}}\,\]
