WebElectrophilic Addition Reactions of Alkenes. Alkenes are unsaturated aliphatic compounds containing a carbon-carbon double bond [ C = C ]. Alkenes are electron-rich species, and they are ready to donate that pair of pi electrons to electrophiles. Hence, we can say that alkenes tend to act as lewis bases.

WebThe attraction between the propene and the bromine. The double bond in all alkenes is made up of two different parts. One pair of electrons lies on the line between the two nuclei where you would expect them to be. This is called a sigma bond.
