Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

**Determine the Most Stable Chair Conformation**

**Objective:**
To determine the most stable chair conformation for the given cyclohexane derivative.

**Compound Structure:**
- The compound is a cyclohexane ring with two substituents: two NH₂ (amino) groups. One NH₂ group is located at the top (in an equatorial position) and another NH₂ group is located at the bottom (in an axial position).

**Chair Conformations:**
1. **First Conformation:**
- The NH₂ groups are both in axial positions.

2. **Second Conformation:**
- The NH₂ groups are both in equatorial positions.

3. **Third Conformation:**
- One NH₂ group is in an equatorial position and the other is in an axial position.

4. **Fourth Conformation:**
- One NH₂ group is in an axial position, and the other is in an equatorial position on the opposite side of the ring compared to the third conformation.

**Analysis:**
- In determining the most stable chair conformation, the goal is to minimize steric hindrance. Steric hindrance occurs when atoms are positioned too closely, causing repulsion and instability.
- Equatorial positions are generally more stable because substituents are staggered, reducing steric interactions.

**Conclusion:**
The second chair conformation, with both NH₂ groups in equatorial positions, is the most stable form. This arrangement minimizes steric hindrance, making it energetically favorable.

Remember to always analyze substituent positions and steric interactions to determine the most stable chair conformation for cyclohexane derivatives.
