Question
**Title: Exploring Chair Conformations in Cyclohexane Derivatives** **Objective:** Using your model kits, construct the cis-1-tert-butyl-3-methylcyclohexane molecule. Your task is to draw the least stable and most stable chair conformations. Ensure that the structures are related through chair inversions. **Instructions:** - **Least Stable Chair Conformation:** Identify and draw the chair conformation of cis-1-tert-butyl-3-methylcyclohexane that results in higher steric strain due to axial positioning of larger groups. - **Most Stable Chair Conformation:** Identify and draw the chair conformation where groups are positioned equatorially, minimizing steric strain and making the structure more stable. **Note:** Inversions between these conformations are an essential aspect of understanding the dynamics of cyclohexane rings. Through this exercise, you will explore the impact of steric interactions on molecular stability and gain a deeper understanding of conformational analysis in organic chemistry.

Expert Solution
Step 1

Most stable chair: First you have to put bulky group (t-Bu) in equatiorial position for cis-1-tert-butyl-3-methylcyclohexane you have to put methyl group also in equatorial position. Both groups are at equatorial positon. Therefore these chair conformation is more stable.

Least stable chair: both groups at axial position. Therefore least stable.
