Web1,2-disubstituted alkenes are described as: cis - if the two alkyl groups, R-, are on the same side of the C=C. trans - if the two alkyl groups, R-, are on opposite sides of the C=C. these terms are inserted into the name as prefixes. cis-. trans-. For example, but-2-ene, …
WebAug 15, 2024 · Alkenes with a C=CR 2 unit, where the two R groups are the same, do not exist as cis-trans isomers. Alkenes of the type R–CH=CH–R can exist as cis and trans isomers; cis if the two R groups are on the same side of the carbon-to-carbon double bond, and trans if the two R groups are on opposite sides of the carbon-to-carbon double bond. WebE/Z describe absolute stereochemistry whereas cis/trans only tells us relative stereochemistry. E/Z can be used without confusion when you have 3 or 4 different groups attached to the double bond carbons which is where cis/trans starts to break down.
