Dienes - Hydrocarbon
These are hydrocarbon along with two carbon-carbon double bonds. Dienes are of three forms
(a) Conjugated dienes: Double bonds are seperated through one single bond.
(b) Cumulative dienes: in this Double bonds are adjacent to each other.
(c) Isolated or Non-conjugated: Double covalent bonds are separated by several one single bond.
