When an alkyl group is attached to a π system, it acts as an electron-donor group by the process of hyperconjugation. ... The delocalisation occurs because of a partial overlap of a sp3-ssigma bond orbital with an empty p orbital of the π bond of an adjacent carbon atom.
Why are alkyl groups electron donating?
Alkyl groups are electron donating and carbocation-stabilizing because the electrons around the neighboring carbons are drawn towards the nearby positive charge, thus slightly reducing the electron poverty of the positively-charged carbon.
Why are alkyl groups more electron donating than hydrogen?
Carbon is more electronegative than hydrogen; therefore, its tendency to donate electrons as part of an alkyl group is increased.
