    The reaction \[{{C}_{12}}{{H}_{26}}\xrightarrow[{}]{{}}{{C}_{6}}{{H}_{12}}+{{C}_{6}}{{H}_{14}}\]represent:

    A)  substitution      

    B)  synthesis

    C)  cracking                              

    D)  polymerization

    Correct Answer: C

    Solution :

    Key Idea: (i) In substitution: reaction an atom or group or group of atoms replaces other. (ii) In synthesis: reaction new compound is formed from elements. (iii) Cracking: Involved breaking of alkane molecules into smaller hydrocarbon molecules. (iv) Polymerisation is condensation of smaller units to form bigger molecule. \[\therefore \]\[{{C}_{12}}{{H}_{26}}\xrightarrow{{}}{{C}_{6}}{{H}_{12}}+{{C}_{6}}{{H}_{14}}\] is cracking reaction
