    \[C{{H}_{2}}=CH-C{{H}_{2}}-CH=C{{H}_{2}}\] represents a/an

    A)  conjugated system       

    B) cumulative system

    C) isolated system               

    D) All of the above

    Correct Answer: C

    Solution :

    In conjugated system, double bonds are present at alternate positions, in cumulative system, double bonds are present at adjacent positions while in isolated system, there is a large difference, between the positions of double bond. Hence, \[C{{H}_{2}}=CHCH2CH=C{{H}_{2}}\] represents an isolated system.
