Answer 2

Explanation:

• The term hydration refer to addition of water molecule.

When propene reacts with water in the presence of concentrated sulphuric acid as catalyst then it forms propan-2-ol.

Chemical equation -

CH3-CH=CH2 + H2O ⇌ CH3CH(OH)CH3

Mechanism -

( Refer to the attachment. )

Step 1 -

• Protonation of alkene to form a stable carbocation by electrophillic attack of H3O+.

Step 2 -

• Nucleophillic attack of water on carbocation.

Step 3 -

• Deprotonation to form an alcohol.

Note -

• In case of unsymmetrical Alkene, the addition of water takes place in accordance with Markovnikov's rule. This rules states that the negative part (OH-) parts gets attached to that carbon atom which possess lesser number of hydrogen atoms.
