Consider the above reaction, the major product 'P' is:
  1. (A)(see structure)
    ✓ Correct
  2. (B)(see structure)
  3. (C)(see structure)
  4. (D)(see structure)

Answer: (A)

Solution

The reaction involves HCl addition to an alkene in the presence of peroxide (anti-Markovnikov addition via free radical mechanism). The chlorine adds to the less substituted carbon of the double bond, and the hydrogen adds to the more substituted carbon. Additionally, water adds to form a tertiary alcohol at the most substituted position. The major product is structure (C), which shows the chlorine on the terminal carbon and the hydroxyl group on the tertiary carbon.
