Expert Solution
Step 1: cyclohexane chair conformation.

It is necessary to draw the cyclohexane in chair confirmation. To follow some rules that are to avoid lone pair lone pair repulsion. To avoid 1, 3 diaxial interaction. That ring will be most stable form. 

1. Here we have to draw the most stable forms of the given cyclohexane conformations. 

2 . Start to draw the chair conformation. 

3. Avoid lone pair lone pair repulsion. 

4. Avoid 1,3- diaxial interaction. It increases energy of that system. 

5. Chairs are most stable with less energy. 

6. Let us see the stable conformations:
