Report Abuse. Thanks so much, I have been looking on google for a while and i cant find the answer. Although geometric isomers have completely different physical and chemical properties (for example, cis-and trans-2-butene have different boiling points and densities), optical isomers (also called enantiomers) differ in only one characteristic--their interaction with plane polarized light. The cis-isomer of MAA 2 b 2 may also exhibit optical isomerism although we will concentrate largely on optical isomers of the type M(AA) 3 (see below). P can represent a pair of optical isomers.
