JEE Main & Advanced Chemistry Hydrocarbons / हाइड्रोकार्बन Question Bank Alkane

  • question_answer
    The final product of complete oxidation of hydrocarbons is [CPMT 1981]

    A) Acid

    B) Aldehyde

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

    D) Dihydric alcohol

    Correct Answer: C

    Solution :

               \[\underset{\text{Methane}}{\mathop{C{{H}_{4}}}}\,+2{{O}_{2}}\to C{{O}_{2}}+2{{H}_{2}}O\]                    \[\underset{\text{Ethene}}{\mathop{{{C}_{2}}{{H}_{4}}}}\,+3{{O}_{2}}\to 2C{{O}_{2}}+2{{H}_{2}}O\] All hydrocarbons saturated or unsaturated on complete combustion always produce \[C{{O}_{2}}\] and \[{{H}_{2}}O\].
