### Chair Conformations Stability Question**Question:**Which of the following chair conformations is the most stable?**Diagrams:**1. **A** (Equatorial Position) - A cyclohexane chair conformation with hydrogen (H) in the equatorial position. 2. **B** (Axial Position) - A cyclohexane chair conformation with hydrogen (H) in the axial position. **Options:**- ○ B- ○ A is more stable than B if the solvent is polar protic. B is more stable than A if the solvent is polar aprotic.- ○ A and B have the same stability.- ○ A**Explanation:**In cyclohexane chair conformations, substituents in the equatorial position (diagram A) generally experience less steric hindrance compared to those in the axial position (diagram B). This typically makes the equatorial conformation more stable. However, the stability can also be influenced by the type of solvent, as mentioned in one of the given options.**Note:**For further understanding, consider the influence of different solvents and substituents on the stability of chair conformations. Generally, large substituents prefer the equatorial position to minimize 1,3-diaxial interactions.

We know for stable conformation bulky group must be present at equatorial position to avoid 1,3…

Concept explainers

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.
