When isomer’s have the same structural formula but differ in relative arrangements of atoms or groups in space within the molecule, these are known as stereosiomers and the phenomenon as stereoisomerism
Stereo isomers can be configurational isomers or conformation isomers.
The fixed relative spatial arrangement of atoms in the molecule is known as configuration.
A particular orientation (or arrangement) of atoms in a molecule, differing from other possible orientations by rotation around single bonds is known as conformation.
Configurational isomer’s can be geometrical isomers (or) optical isomers.
