Explanation:
When 2-phenyl propene undergoes acidic hydration, it undergoes an addition reaction in the presence of an acid catalyst, such as sulfuric acid (H2SO4), to form an alcohol. The addition of water to the double bond of the propene results in the formation of a carbocation intermediate. The carbocation can be stabilized by the presence of the phenyl group, which delocalizes the positive charge.
Step-by-step mechanism:
1. Protonation: The acid catalyst protonates the double bond of 2-phenyl propene, forming a more stable carbocation intermediate.
2. Addition of water: Water (H2O) then adds to the carbocation, resulting in the formation of a new bond between the carbocation and the oxygen atom of water.
3. Deprotonation: The resulting intermediate is then deprotonated by water, leading to the formation of the alcohol product.
Product formation:
In the given options, the correct product is 2-phenyl-2-propanol (option A). This is because the addition of water to the double bond of 2-phenyl propene results in the formation of a secondary alcohol, where the hydroxyl group is attached to the second carbon atom of the propene.
Option B (2-phenyl-1-propanol) is incorrect because it would involve the attachment of the hydroxyl group to the first carbon atom of the propene.
Option C (3-phenyl-1-propanol) is incorrect because it would involve the attachment of the hydroxyl group to the third carbon atom of the propene.
Option D (1-phenyl-2-propanol) is incorrect because it would involve the attachment of the hydroxyl group to the first carbon atom of the propene.
Therefore, the correct product of the acidic hydration of 2-phenyl propene is 2-phenyl-2-propanol (option A).
