MECHANISM FOR REACTION OF ALKENES WITH H3O+
Step 1:
An acid / base reaction. Protonation of the alkene to generate the more stable carbocation.  The
pi electrons act as a Lewis base.
addition of H2O to C=C
Step 2:
Attack of the nucleophilic water molecule on the electrophilic carbocation creates an oxonium ion.
Step 3:
An acid / base reaction. Deprotonation by a base generates the alcohol and regenerates the acid catalyst.
