WebJul 7, 2024 · The E/Z system analyzes the two substituents attached to each carbon in the double bond and assigns each either a high or low priority. If the higher priority group on both carbons in the double bond the same side the alkene is said to have a Z isomer (from German zusammen = together). You could think of Z as Zame Zide to help memorize it. WebIf the compound contains more than one double bond, then each one is analyzed and declared to be E or Z. Example 3 The configuration at the left hand double bond is E; at the right hand double bond it is Z. Thus this compound is (1E,4Z)-1,5-dichloro-1,4-hexadiene.

WebE comes from the German entgegen which means opposite. So the two isomers are: Summary (E)- : the higher priority groups are on opposite sides of the double bond. (Z)- : the higher priority groups are on the same side of the double bond. Note: Three possible suggestions for remembering this: E is for "Enemies", which are on opposite sides. WebApr 5, 2015 · E means entgegen and refers to opposite directions (or sites), while Z means zusammen, which is together, that is the same direction (or site).
