# How can you recognize geometric isomers?

Jul 23, 2016

I can offer one tip! Suppose you have represented your chiral centre, $C {R}_{1} {R}_{2} {R}_{3} {R}_{4}$, correctly on the printed page, or as a model in three dimensions. The interchange of ANY two substituents gives the enantiomer. Interchange again (ANY two substituents), and the original isomer is restored.
