Hydration of 3-phenylbut-1-ene in dilute...

Hydration of 3-phenylbut-1-ene in dilute `H_(3)SO_(4)` forms 2-pheylbutan -2-ol and not 3-phenylbutan-2-ol. Why ?

Text Solution

Verified by Experts

The secondary carbocation initially formed as a result of hydration changes to a more stable tertiary carbocation by `H^(-)` ion shift. Therefore, the final product is different from the expected product.
