Most Stable Conformation

Postby Angela Velazquez 1J » Sun Mar 13, 2016 12:55 am

On 2011 Winter Final Q8B, it says to draw the most stable conformation possible for 1,3,5-trimethylcyclohexane. I know it would be the chair structure but why do the substituents have to be in the equatorial position?

I don't know the exact details, but equatorial substituents are always the most stable, and if you have two substituents on the same carbon, then the most stable conformation will be the one where the heaver substituent is equatorial.
