E-Z isomerism Creative Chemistry
WebSep 6, 2024 · When they are cis, you get Z. When they are trans you get E. Which alkene has the E configuration? What are EZ isomers? E-Z isomerism (also known as cis-trans isomerism or Geometric isomerism) is a type of stereoisomerism in which the same groups are arranged differently. WebThey are the same, E- ≡ trans- and Z- ≡ cis-. Except E-Z is used for more complex isomers. As each side only has 1 H and 1 Cl atom, you can tell if the Cl atoms are on the same or opposite sides, and therefore decide upon cis- or trans-. ... As the heaviest 'corner' on each side is on opposite sides, it is an E- isomer.
