IPA: /ˌstɛr.i.oʊˈkɛm.ɪ.kəl/
KK: /stɛrɪoʊˈkɛmɪkəl/
Relating to the study of the three-dimensional arrangement of atoms in molecules and how this affects their chemical behavior.
The stereochemical properties of the compound determine how it interacts with other molecules.
Stereochemical → It is formed from "stereo-" (from Greek "stereos", meaning solid or three-dimensional) and "chemical" (from Greek "khemia", meaning the art of transmuting metals). The word "stereochemical" refers to the study of the three-dimensional arrangement of atoms in molecules and how this affects their chemical properties.
Think of 'solid' ('stereo-') shapes in chemistry, which helps you remember that 'stereochemical' relates to the three-dimensional structure of molecules.
