Transcribed Image Text:**E2 Reaction and Major Product Analysis**
**Question:**
Determine the major product of the following E2 reaction, taking into account all possible conformers.
**Reaction Details:**
- **Reactant:** A molecule consisting of a benzene ring attached to a CH\(_2\)-CHBr-CH(CH\(_3\))-CH\(_2\)CH\(_3\) structure.
- **Reagent:** Methoxide ion (\(OCH_3^-\)).
**Potential Products:**
1. **Option 1:**
- Structure: \(\text{Benzene ring}-\text{CH}=\text{CH}-\text{CH}_2-\text{CH}_2\text{CH}_3\)
2. **Option 2:**
- Structure: \(\text{Benzene ring}-\text{CH}_2- \text{CH}_2= \text{C}(CH_3)\text{CH}_3\)
3. **Option 3:**
- Structure: \(\text{Benzene ring}-\text{CH}_2- \text{CH}=\text{CH}-\text{CH}_2 \text{CH}_3\)
**Analysis:**
- Evaluate the stability of the alkenes formed.
- Consider the Zaitsev's rule, which predicts the most substituted alkene as the major product in an E2 reaction.
- Analyze the leaving group's alignment and the proton's availability for abstraction.
**Conclusion:**
Select the most stable alkene product based on the reaction conditions and possible conformers.
