CH2=CHCH2CH=CH2 represents a/an

Question

CH2=CHCH2CH=CH2 represents a/an (A) conjugated system (B) cumulative system (C) isolated system (D) All of the above

Tardigrade Admin · Accepted Answer

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} = C H - C H_{2} - C H = C H_{2}

represents an isolated system.
