TheChemSolver/Tools/R/S Configuration & Fischer Projection Solver

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

  1. 1Assign substituents to a tetrahedral carbon (or two bonded carbons)
  2. 2Watch the same molecule update live across all 4 projections
  3. 3Swap two substituents to see R/S flip, or rotate the dihedral to see conformation change without flipping R/S
