Answer 1

Answer:

Mechanism of Hydration of Alkenes

The following steps are involved in the reaction: Step 1: Alkene undergoes protonation to form carbocation by electrophilic attack of H3O+. Step 2: Water, being a nucleophile, attacks on the carbocation. Step 3: Deprotonation occurs to form an alcohol.

Answer 2

eg: ethanol from ethene:

C2H4 + h2O(g) --> C2H5OH

ethene    water       ethanol
