An alkadiene is an aliphatic diene, an organic compound with double bonds in which the carbon atoms are arranged in an open chain.
CH2 = C = CH2 CH3 - CH = C = CH2 are some of the known alkadiene.. Actually alkadienes are organic compounds having 2 double bonds......
The general formula for alkadienes is CnH2n-2, where n represents the number of carbon atoms in the alkadiene chain. This formula indicates that alkadienes have two fewer hydrogen atoms than alkanes of the same carbon chain length, due to the presence of two double bonds in their structure.
