R or S

Descriptors in chemistry that indicate the absolute configuration of chiral centers in molecules, determining their spatial arrangement as right-handed (R) or left-handed (S).

Stereochemistry

The study of the spatial arrangement of atoms within molecules and its influence on the chemical and physical properties of substances.

(S)-3-chloro-3-methylhexane
