H3C H3C OH CH3 3-isopropyl-4-methylcyclohexanol There are four cis, trans isomers for 3-isopropyl-4-methylcyclohexanol, where the cis,trans designations of the substituents are made relative to the OH group: • up, up, up (cis,cis) • up, up, down (cis,trans) • up, down, down (trans,cis) • up, down, up (trans, trans) Consider the most stable chair for each of these isomers, and then draw the most stable and least stable isomer based on a comparison of the best chair for each one. • To simplify matters, consider only axial vs equatorial energies of the groups (i.e. do not worry about the interactions between the groups, which in reality is also important). Use the wedge/hash bond tools to indicate stereochemistry where it exists. You do not have to explicitly draw H atoms. • Use "flat" representations of rings, not chairs, in your drawing.
