Mechanism of acid catalysed hydration reaction involves (i) Protonation of alkene toform carbocation by electrophilic attack of H_(3)O^(+) (ii) Nucleophilic attack of water on carbocation. (iii) Deprotonation to fonn alcohol.

Answer»

(i) and (ii)
(i) and (iii)
(i), (ii) and (iii)
(ii) and (IIII)

Solution :The mechanism of the reaction involves the following three steps :
Step: 1 protonation of alkene to form carbocation by electrophilic ATTACK of `H_(3)O^(+)`
`H_(2)O+H^(+) to H_(3)O^(+)`

Step 2: Nucleophilic attack of water on carbocation.

Step 3: Deprotonation to form an alcohol.
