Alkenes undergo electrophilic addition with many reagents like HX, `H_2O`, HOCI etc. Except in the case of addition of `X_2^(-)` in other additions carbocation is formed as intermediate. The rate of such reactions depends on the stability of carbocation. Rearrangements and ring expansion are also common in such reactions.
