E–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. WebExplanation: In E −Z isomers you must have: restricted rotation, often involving a C=C double bond. two different groups on one end of the bond and two different groups on the other end.
