- A.The product is due to allylic bromination.
- B.The product is due to Markovnikov addition.
- C.The product is due to steric hindrance.
- D.The reaction yields a mixture of .
Show correct answer & step-by-step solution
Correct answer: A — The product is due to allylic bromination.
Solution
- provides a low concentration of in the presence of light.
- The mechanism involves the formation of an allylic radical at the position.
- The allylic radical is stabilized by resonance with the double bond.
- Bromine atom abstraction leads to the formation of .
- Hence the answer is (A).
