Organic and Biochemical MoleculesGeometric isomers of alkenes – If each sp2 C has 2 different groups attached it will have two possible orientations due the fact that pi bonds do not allow for free rotation – If each sp2 C has only one hydrogen you can classify the
structure as cis or trans
H
H HH
Trans2 Hydrogens are on
opposite sides of pi bond
Cis2 Hydrogens are on
the same side of pi bond
F
Cl FCl
Although these structures are Geometric isomers (the 2 halogens
are on opposite sides in the left structure and same side in the right) you don’t refer to them as cis/trans
