SN1 MECHANISM FOR REACTION OF ALCOHOLS WITH HBr
Step 1: An acid/base reaction. Protonation of the alcoholic oxygen to make a better leaving group. This step is very fast and reversible. The lone pairs on the oxygen make it a Lewis base.
Step 2: Cleavage of the C-O bond allows the loss of the good leaving group, a neutral water molecule, to give a carbocation intermediate. This is the rate determining step (bond breaking is endothermic)
Step 3: Attack of the nucleophilic bromide ion on the electrophilic carbocation creates the alkyl bromide.
Good Day
