Most Stable Chair Confirmation with Substituent
I know the course is over, however, I am curious... Would a chair confirmation with the substituent in the equatorial position attached to the "foot rest" or "head rest" part of the confirmation be more stable than if the substituent in the equatorial position is attached to a ca...
