Question

Stable chair configuration

Answer 1

@Winterlove right away these questions aren't that bad but they depend on whether or not you can go from ring to the chair conformation

Answer 2

I know that when T-bu and br are in equatorial postions in the chair, that chair configuration is most stable, but when that occurs, they are both in gauche interation, whereas if they were in axial, it would be anti.

Answer 3

Let's translate this to the cyclohexane chair conformation. UP = Dash, Wedge = down.

Answer 4

I take your figure, I number the carbons, and dashes = down, and wedges = up
