  • question_answer Name the reaction \[{{C}_{10}}{{H}_{22}}\xrightarrow{900K}{{C}_{4}}{{H}_{8}}+{{C}_{6}}{{H}_{14}}\] [MP PET 1995; MP PMT 1997]

    A) Alkylation

    B) Cracking

    C) Pyrolysis

    D) Fractionation

    Correct Answer: B

    Solution :

    \[\underset{\text{Decane}}{\mathop{{{C}_{10}}{{H}_{22}}}}\,\underset{\text{Cracking}}{\mathop{\xrightarrow{900\,K}}}\,\underset{\text{Butane}}{\mathop{{{C}_{4}}{{H}_{8}}}}\,+\underset{\text{Hexane}}{\mathop{{{C}_{6}}{{H}_{14}}}}\,\]
