Out of the following alkenes, the one which will produce tertiary butyl alcohol on acid-catalysed hydration is:
  1. (A)CH₃CH₂CH=CH₂
  2. (B)CH₃CH=CH₂
  3. (C)CH₃–CH=CH–CH₃
  4. (D)(CH₃)₂C=CH₂✓ Correct

Answer: (D)

Solution

Markovnikov hydration: H adds to CH, giving the 3° carbocation (CH)C; water then yields (CH)COH.

Correct option: (D).
