Stereochemistry studies the spatial arrangement of chemical atoms in molecules. A Fischer projection records this information at successive stereocenters, whereas a molecular formula only counts chemical atoms. See McMurry: representing carbohydrate stereochemistry.

Stereochemistry is a branch of chemistry that focuses on the spatial arrangement of atoms within molecules and how this arrangement affects their physical and chemical properties. It primarily deals with isomerism, which is the phenomenon where compounds can have the same molecular formula but different structures or arrangements of atoms. There are several key concepts in stereochemistry: 1. **Isomers**: Molecules with the same molecular formula but different structural arrangements.
