The hydration of alkenes in the presence of acids proceed via carbocation mechanisms as given below:
and that carbocation is formed which is most stable, It is observed that alkenes are more reactive than alkynes towards any electrophile. This reaction, i.e., the electrophilic addition reaction of alkenes and alkynes with symmetrical addendum This shows that all reactions of alkenes and alkynes for electrophilic addition reactions may either take place via intermediates of transition state.
