Stereoisomerism and different type that exist I.e. (geometry and optical) give simple and naturally occurring examples of each type of illustration your explanation, including structural formula and photograph of 3d Models of stereoisomerism
Stereoisomers are isomers that have the same composition but that differ in the orientation of those parts in space.
Geometric isomers are two or more coordination compounds which contain the same number and types of atoms, and bonds but which have different spatial arrangements of the atoms.i.e1,2-dichloroethene
Optical isomers are two compounds which contain the same number and kinds of atoms, and bonds and different spatial arrangements of the atoms, but which have non-superimposable mirror images.
i.e Carbon with four different groups bonded to it.
There are two ways in which isomers can differ. When they differ in the way the atoms are connected, they are called constitutional isomers. Butane and isobutane, for example, are constitutional isomers. Constitutional isomers have similar chemical properties but different physical properties.
