EZ NOTATION FOR GEOMETRIC ISOMERISM This page explains the EZ system for naming geometric isomers Here is one of the isomers of but2ene The CH 3 group has the higher priority because its carbon atom has an atomic number of 6 compared with an atomic number of 1 for the hydrogen also attached to the carboncarbon double bondThe proper name for this molecule is either trans2fluoro3methylpent2ene because the alkyl groups that form the backbone chain (ie, methyl and ethyl) reside across the double bond from each other, or (Z)2fluoro3methylpent2ene because the highestpriority groups on each side of the double bond are on the same side of the double bond Fluoro is the highestpriority groupYes I was just unsure about it because I thought cistrans isomers were also e/z isomers Well, in a sense they are, but e/z isomers have more than three functional groups Glad you figured it out I think either cistrans or E/Z could be used to describe

In the E– Z system of nomenclature, the geometry of the isomers is determined by prioritizing the substituents on the two carbons of the double bond The priorities of the substituents are determined by the atomic number with atoms of a higher atomic number having higher priority According to this method 1Stereoisomers to show the isomerism clearly methylpropene 2methylpent2ene 3methylpent2ene 3,4dimethylhex3ene 1chloropropene 2ethylpent1ene but1ene 2bromo3chlorobut2ene CH 3 CH 2 CH 2 CH 3 butane methylpropane H 3 CH 3 eg C 4 H 10 CH 3 CH 2 CH 2 OH propan1ol propan2ol H OH eg C 3 7 OH C H 3 CH 2 C O H propanalGeometric Isomers Practice I For each molecule below, 1) determine whether geometric isomerism is possible 2) name the molecule (use cistrans naming where applicable) a) e) geometric isomerism trans2methylhex3ene geometric isomerism cis4,5,6trichlorohex2ene b) f) geometric isomerism cis4chlorohex2ene geometric isomerism trans8
