Regiochemistry vs. Stereochemistry

Regiochemistrynoun

(chemistry) The chemistry of regioselective reactions

Stereochemistrynoun

the branch of chemistry that involves the spatial arrangement of the atoms of molecules, and studies how this affects the physical and chemical properties of such species

Stereochemistrynoun

the effect of such spatial arrangement on the chemistry of a particular compound

Stereochemistry

Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation. The study of stereochemistry focuses on stereoisomers, which by definition have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
