R/S Configuration Solver — Fischer, Sawhorse & Newman Projections
Build a tetrahedral stereocenter and see it live as a 3D wedge-dash structure, Fischer projection, sawhorse projection, and Newman projection at once — with the IUPAC name and R/S configuration updating as you swap substituents or rotate the conformation.

Topics Covered
- ✓CIP priority rules and R/S assignment
- ✓Fischer projection conventions
- ✓Newman projection and dihedral angle
- ✓Sawhorse projection
- ✓Meso compound detection
- ✓Conformation vs configuration (dihedral rotation never flips R/S)
How to Use
- 1Assign substituents to a tetrahedral carbon (or two bonded carbons)
- 2Watch the same molecule update live across all 4 projections
- 3Swap two substituents to see R/S flip, or rotate the dihedral to see conformation change without flipping R/S
