IPA: /ˌstɛr.i.oʊ.spɪˈsɪf.ɪk/
KK: /ˌstɛrɪoʊspɪˈsɪfɪk/
Relating to a process that produces a specific three-dimensional arrangement of atoms in a molecule.
The reaction was stereospecific, resulting in only one of the possible isomers.
Stereospecific → It is formed from "stereo-" (from Greek "stereos", meaning solid or three-dimensional) and "specific" (from Latin "specificus", meaning particular or distinct). The word describes a reaction or process that is specific to a particular three-dimensional arrangement of molecules.
Think of 'solid' ('stereo-') and 'particular' ('specific') to remember that 'stereospecific' refers to a process that is specific to a solid or distinct three-dimensional arrangement.
