Question
Hello I need help solving this chemistry problem. I just need the answer quick no explanation thank you.
![**Question:**
Determine the product most likely to arise from the following reaction. Time allowed: 3 minutes.
**Reaction:**
Starting material: Acetophenone (a phenyl group attached to a carbonyl group, which is bonded to a methyl group)
Reagents: Br₂, FeBr₃
**Possible Products:**
- **A:** 4-Bromoacetophenone (with bromine at the para position to the carbonyl group)
- **B:** 3-Bromoacetophenone (with bromine at the meta position to the carbonyl group)
- **C:** 1-(3-Bromophenyl)propan-1-one (bromine at the meta position to the carbonyl, elongated carbon chain)
- **D:** Acetophenone (no reaction)
- **E:** Phenacyl bromide (bromine at the alpha position of the carbonyl)
- **F:** Acetone Phenone (unaltered substrate structure)
**Explanation:**
This is an electrophilic aromatic substitution reaction. The presence of FeBr₃ suggests a Lewis acid-catalyzed bromination. The carbonyl group in acetophenone is a meta-directing group, which directs the bromine to the meta position relative to itself. Therefore, **option B** (3-Bromoacetophenone) is the most likely product.
Be sure to verify your selection based on reaction conditions and directing effects of substituents during electrophilic aromatic substitution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F38b3b78e-6cda-40eb-bd99-bd4ab94cdc9d%2Fca0a74e4-cf6e-4f20-8cbf-3b0147087f16%2Fhphkkng_processed.jpeg&w=3840&q=75)
