Unformatted text preview: Cl H H Cl H H anti All eclipsed conformers are of higher energy than any of the staggered conformers. This is due to higher tortional strain. Of the 3 staggered conformers, the anti is the most stable, because it maximizes the dihedral angle @ 180 o 2) Cyclohexane Conformers: Draw the most stable chair conformation for the compounds named below. H H H H H H CH 3 H H H H CH 3 CH 2 trans-4-ethyl-1-methylcyclohexane H OH H H H H Cl H H H H H cis-1-chloro-3-cyclohexanol...
