Which compound will undergo the haloform reaction most rapidly?
- A..
- B..
- C..
- D..
Show correct answer & step-by-step solution
Correct answer: B — .
Solution
- The rate-determining step of the haloform reaction is the formation of the enolate.
- Acetophenone forms an enolate where the negative charge is delocalized into the phenyl ring.
- This resonance stabilization lowers the activation energy for enolate formation compared to aliphatic methyl ketones.
- Hence the answer is (B).
