cyclohexane chair and boat conformation

### Question B

**Task:**
- Look down the axes of carbons 1 and 2, and carbons 5 and 4.
- Draw the parallel Newman projections for both conformations.
- Compare the two drawings and describe what you observe with regards to eclipsing and staggered interactions.

**Explanation:**
1. **Newman Projection Overview:**
   - Newman projections are a way to visualize the conformation of a molecule as viewed down the bond axis connecting two atoms, typically carbon atoms in an alkane.

2. **Steps to Draw Newman Projections:**
   - **Identify the Bond Axis:** Look down the bond from the first carbon towards the second (e.g., from carbon 1 to carbon 2).
   - **Draw Circles and Bonds:** Represent the nearest carbon as a point or small circle and the farthest carbon as a larger circle surrounding the first. The bonds to atoms or groups are drawn as lines or sticks from these circles.

3. **Analyzing Eclipsing vs. Staggered Conformations:**
   - **Eclipsing Conformation:** Atoms or groups from both carbons are aligned with each other, leading to higher torsional strain due to close proximity.
   - **Staggered Conformation:** Atoms or groups on one carbon are positioned between atoms or groups on the other, offering more spatial separation and lower energy due to minimized repulsion.

4. **Comparative Analysis:**
   - Examine both projections.
   - Note the spatial arrangement of groups around the axes and their energetic implications.
   - Describe the potential strain or stability of each conformation.

By executing these steps, students can gain insights into molecular geometry and conformational analysis through visual examination of Newman projections.

Expert Solution
Step 1-Introduction

The Newman projection of a molecule having multi-atoms especially carbon involves drawing the front atom as a point and the back atom that is directly bonded to the front atom as a circle. The main advantage of this representation is the convenient viewing of the dihedral angle (the angle between the two planes).
