Question
**Cyclohexane Chair Conformation Analysis**

Refer to the structure below to answer the following questions:

**Questions:**

1. Which of the labeled groups in the structure are equatorial?
2. Which of the labeled groups is trans to b?
3. Which groups have a 1,3-diaxial interaction with each other?
4. Which groups are trans to e?

**Structure Diagram Explanation:**

The diagram is depicting a cyclohexane molecule in its chair conformation. It displays the positions of various substituents labeled as a, b, c, d, and e. These positions are identified as follows:

- **a** is located equatorially.
- **b** is located axially.
- **c** is located equatorially.
- **d** is equatorial.
- **e** is axial.

**Graphical Explanation:**

1. **Chair Conformation:**
   - The cyclohexane is drawn in a chair-like shape, with alternating bonds shown in bold for the lower parts and regular lines for the upper parts, representing a three-dimensional perspective.

2. **Substituents:**
   - The substituents (a, b, c, d, e) are attached to different carbon atoms of the cyclohexane ring. Axial positions are typically represented as lines going straight up or down from the carbon atoms, while equatorial positions are represented as lines extending outward from the carbon atoms along the plane of the ring.

**Answering the Questions:**

1. **Equatorial Groups:**
   - Group a, c, and d are equatorial.

2. **Trans to b:**
   - Group d is trans to b.

3. **1,3-Diaxial Interactions:**
   - Groups b and e have a 1,3-diaxial interaction as they are both in axial positions on the ring and separated by three carbon atoms.

4. **Trans to e:**
   - Group c is trans to e.

Understanding the positions and interactions in the chair conformation of cyclohexane is critical for predicting the stability and reactivity of such molecules in various chemical contexts.
