Stereochemistry
subdiscipline of chemistry about stereoisomers and the relative spatial arrangement of atoms / From Wikipedia, the free encyclopedia
Stereochemistry is the study of how molecules are affected by the way their atoms are arranged in space.[1] It is also known as 3D chemistry as the word stereo means three dimensional.[2] Using stereochemistry, chemists can work out the relationships between different molecules that are made up from the same atoms. They can also study the effect on the physical or biological properties these relationships give molecules. When these relationships influence the reactivity of the molecules it is called dynamic stereochemistry.

In chemistry, some molecules have more than one isomer. This means that molecules can have different forms, even though all the forms are made of the same atoms. There are two kinds of isomers.[3] Constitutional isomers have the same atoms, but they are joined differently.[3] Stereoisomers have the same atoms, they are joined the same way, but the atoms are arranged differently in space.[3] An important part of stereochemistry is the study of chiral molecules.[4] These molecules look almost identical, except that one molecule is the mirror image of the other.
In most chemical bonds, the atoms of a molecule free to move around without breaking the bonds. When a molecule has a double bond or a ring structure, the molecule can be sorted into different isomers. These are molecules with the same chemical structure but different forms.
The study of stereochemical problems covers the entire range of organic, inorganic, biological, physical and supramolecular chemistries.
