Geometrical Isomers

Compounds with different arrangements of groups on either side of a bond with restricted rotation, such as a double bond or a single bond in a ring, for example cis-trans isomers of certain alkenes. Stereoisomers that are not mirror images of each other, also known as position isomers.
