Web1 jun. 2024 · Is the molecule below an E or Z isomer? From what I believe I would say E isomer because the two priority halides Cl and Br are on opposite sides of the double bond. But I'm not 100% sure. Because they … WebIt is particularly important that you make molecular models of some simple alkenes to gain insight into the geometry of these compounds. Geometric isomerism (also known as cis-trans isomerism or E-Z isomerism) is a form of stereoisomerism.
