Web* The alcohol is protonated in acidic medium to give ethyloxonium ion, which cannot break easily to give carbocation. * Thus formed oxonium ion is attacked by the bromide ion from the back side while OH 2 + group is still bonded to the carbon. It leads to a transition state in which the bromide ion facilitates the breaking of C-O bond.
