Pls explain chair conformations 

**Title: Drawing the Most Stable Chair Conformation for a Cyclohexane Derivative** **Objective:** Learn how to draw the most stable chair conformation for a given cyclohexane compound. **Task:** Draw the most stable chair conformation for the compound shown. **Compound Description:** - The compound depicted is a cyclohexane ring with two substituents. - The substituents are located on adjacent carbon atoms. - The first substituent is an ethyl group (two carbon chain) located on the top right carbon. - The second substituent is a methyl group (single carbon) located on the bottom right carbon, represented in a wedge, indicating it is above the plane of the ring. **Tips for Drawing the Chair Conformation:** 1. **Identify the Axial and Equatorial Positions:** - In a chair conformation, each carbon has one axial and one equatorial bond. - Larger groups should be placed in equatorial positions to minimize steric strain. 2. **Place Larger Substituents Equatorially:** - Given the size of ethyl and methyl groups, ethyl is the larger group and should be placed equatorially if possible. 3. **Consider Stereochemistry:** - Ensure that the orientation (upward or downward) of the substituents matches the original compound configuration. 4. **Sketching the Chair:** - Draw a zig-zag line to represent the cyclohexane ring. - Add substituents appropriately, considering steric hindrance and stability. **Conclusion:** By placing the larger substituents in equatorial positions and maintaining the stereochemistry, you can draw the most stable chair conformation for this cyclohexane derivative. This minimizes potential steric strain and leads to a lower energy, more stable structure.

Expert Solution
Step 1

Chemistry homework question answer, step 1, image 1

Chair conformation: Chair conformation consists of two planes:

carbon 1,3 and 5 - in one plane

carbon 2,4,and 6 - in another plane

chair conformation have two positions - one is axial and another is equatorial.
