E/Z

Postby Alex Nguyen 3I » Sat Mar 12, 2016 10:24 pm

Where does E/Z exist besides for double bonds? Would it be on all rings with substituents or only cyclohexane (ring or chair conformation?). If a cyclohexane had 3 substituents for example 1,3,5-trimethylcyclohexane, then what do you do for E/Z?

E and Z refer to 2 specific substituents across a constant plane, so in the case of 1,3,5-trimethylcyclohexane you would have biz or trans relative to two of the methyl groups, which would be determines based on which side of the plane created by the cyclohexane they lie on.
