Question

The major product for the following reaction is :

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is B

Addition of $H_{2}O$ to alkene is a Markovnikov addition reaction.

In Markovnikov's addition, negative part of the addendum (adding molecule) gets attached to that doubly bonded C which posses lesser number of hydrogen atoms.

As shown, the double bond attacks the $H^{+}$ ion and form a secondary phenyl cation. Phenyl carbocation is more stable due to the resonance effect with benzene ring. Now the $O{H}^{-}$ gets added to the carbocation to form 1-phenylpropan-1-ol
