WebThe prefixes “cis” and trans are derived from Latin. Cis means “on the same side”, trans means “on opposing sides”. In the cis isomer, the substituent groups are placed on one side, while in the trans isomer, the … WebE–Z configuration, or the E–Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry. It is an extension of cis – trans isomer notation (which only describes relative stereochemistry ) that can be used to describe double bonds having two, three or four substituents .
