Question
Chapter 6, Problem 6.32AP
Interpretation Introduction
Interpretation:
The structure of the chiral
Concept introduction:
A carbon atom that has four nonequivalent atoms or groups attached to it is known as the chiral carbon atom. Chiral carbon centers are also called asymmetric or stereogenic centers. A carbon atom that does not have four nonequivalent atoms or groups attached to it is known as an achiral carbon atom.

I'm confused as to why the chiral centers are the was they are. I understand that the horizontal lines are wedged and vertical are dashed. Wouldn't the first priority be the carboxylic acid, then alcohol, the carbon, and then the hydrogen? The book is saying that one method is to keep two of the straight lines and pick one group to be dashed and one to be wedged. Then switch the last priority group (H) with whatever group you chose to be on the dash. Whatever configuration you get, make it the opposite since you switched groups. And when I use this method I end up getting S when the top one should be R.
The energy difference between a tert-butyl group going from equatorial to axial in a cyclohexane is 18.3 kJ/mol. When two of the carbon atoms are replaced with oxygen atoms (molecule B) the energy difference between the two chair conformations drops to 5.9 kJ/mol. Explain this difference. (Hint: Consider what makes putting groups axial unfavorable).
It is easy to imagine a cyclohexane as a flat hexagon and a lot of the time we draw it
that way. Looking at 1,3,5-triethylcyclohexane we cannot tell the stability of the
molecule from looking at the flat 2D drawing. Explain why we need to look at the 3D
configuration and what conformation (axial,equatorial) would each of the three ethyl
groups be in for the most stable configuration.
