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. WebDefinition and Meaning of E and Z. The E and Z notation is a way to describe the stereochemistry of molecules that have a double bond in their structure.

"WebExample: but-2-ene. Isomer 1 : Step 1 : split the alkene. Step 2 : assign the relative priorities. The two attached atoms are C and H, so since the atomic numbers C > H then the -CH3 group is higher priority. Step 3 : look at the relative positions of the higher priority groups : same side = Z, hence (Z)-but-2-ene. Isomer 2 : " - Chemistry e z
