Question

How can I identify a double chain hydrocarbon​

Answer 1

If more than one double bond is present, indicate their position by using the number of the first carbon of each double bond and use the suffix -diene (for 2 double bonds), -triene (for 3 double bonds), -tetraene (for 4 double bonds), etc.

Answer 2

Step-by-step explanation:

Unsaturated hydrocarbons have one or more double or triple bonds between carbon atoms. Those with double bond are called alkenes and those with one double bond have the formula CnH2n (assuming non-cyclic structures). ... Alkanes have the general formula CnH2n+2.
