1. **Choose the correct chair conformation of the cyclohexane that can undergo E2 elimination:**
- [Select] options: A, B, C, D
2. **Choose the correct transition state for E2 elimination using NaO(tBu) as the base:**
- [Select] options: A, B, C, D
3. **Choose the correct elimination product:**
- [Select] options: A, B, C, D
4. **State whether a solution of the product would be optically active or not:**
- [Select] options: Yes, No
**Graphs and Diagrams:**
- **1. E2 Chair:**
- Multiple chair conformations of a cyclohexane ring with substituents (Br, t-Bu, and El) displayed in different axial and equatorial positions.
- **2. E2 Transition State:**
- Displays possible transition states with partial bonds (dashed lines) representing the abstraction process involving NaO(tBu).
- **3. E2 Product:**
- Shows potential products after the elimination process, highlighting the new double bond formed and the remaining substituents.
For effective learning, consider how the arrangement of substituents in the chair conformation affects the likelihood of E2 elimination, focusing on the axial positioning of bulky groups and the leaving groups.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4570aa97-d31b-43f1-9c0f-902fd4186789%2F651eb227-c82a-46a5-8cc4-3b8349ef82c3%2Fem7ym3q_processed.jpeg&w=3840&q=75)
