Akenes can undergo addition reactions because they are unsaturated.


Alkenes are doubly bonded and sp2 hybridised which the electrons in the side to side overlap of p orbitals which makes the pi bond can be donated to an electrophile for example of electrophilic addition. This breaks one of the carbon to carbon bonds as the substituent has formed a single bond and another substituent bonds with the second carbon of the former carbon to carbon double bond.
