Hydrocarbons with at least one double or triple $C-C$ bond

At least one carbon-carbon double bond ($C=C$)

$C_nH_{2n}$

Alkenes are more reactive than alkanes

$C_2H_4$

$C_3H_6$

$C_4H_8$

At the end (side) of the carbon chain

In the middle of the carbon chain

Cracking

Breaks down large alkanes into smaller alkanes and alkenes
