Solution
- Stereochemistry is the branch of chemistry that deals with the study of the spatial atomic arrangement that forms the molecular structure.
- R/S system is the nomenclature system for enantiomers.
- In this type of nomenclature, each chiral center is assigned R or S following a system by which its substituents are each assigned a priority based on atomic number, following the Cahn-Ingold-Prelog rules.
- The R means Rectus in Latin (means right) and S means Sinister in Latin (means Left).
- Molecules that rotate the plane polarised light to right is said as R isomer.
- Molecule that rotate the plane polarised light to left is said as S isomer.
