Question

What are the types of stereoisomerism?

Answer 1

We know that the phenomena in which the compounds have the same structural formula but different arrangements of atoms or groups in space are called stereoisomers and the compounds exhibiting these phenomena are known as stereoisomers.

Complete answer:
As we know , stereoisomerism is the arrangement of atoms in molecules whose property remains identical, however their arrangement in area is completely different in every compound. Stereoisomerism involves compounds with identical chemical formulae and bonds however differing in arrangement. Stereochemistry is defined as the branch of chemistry which involves the study of various spatial arrangements of atoms present in molecules. Stereochemistry is described as the systematic presentation of a particular field of science and technology traditionally requiring a short preliminary excursion into history. Stereochemistry is also said to be the chemistry of space, which is stereochemistry that deals with the spatial arrangements of groups and atoms in a molecule. It is often divided into:
Geometrical state that arises usually in heterolytic complexes. This kind of state arises because of the various potential geometric arrangements for the ligands.
Optical state that arises in chiral molecules or ions area unit mirror pictures of every alternative. However, they can't be superimposed on one another.
The structure of the molecule can change according to the three dimensional arrangement of the atoms that constitute this. Also, Stereochemistry deals with the atom’s arrangement manipulation. A branch of stereochemistry deals with the molecule’s study that exhibits chirality, which is a property of the geometry of molecules that makes them non-superimposable on their mirror images.

Note:
Remember that the configurationally isomers are defined as those stereoisomers which can be interconverted only by breaking and remaking of the covalent bond and not by simple rotation about the sigma bond.
