Chiral Center Analysis
Bromochlorofluoromethane (CHBrClF) contains 1 chiral center. The simplest chiral molecule with four different atoms bonded to a central carbon. Perfect for learning R/S assignment basics.. Each chiral center is analyzed below using CIP (Cahn-Ingold-Prelog) priority rules to determine R or S configuration.
CIP Priority Assignment
The four substituents on the chiral center are ranked by atomic number of the directly attached atom, with ties broken by exploring outward along each branch.
- Priority 1: Br - Highest atomic number (35)
- Priority 2: Cl - Second highest atomic number (17)
- Priority 3: F - Third highest atomic number (9)
- Priority 4: H - Lowest atomic number (1)
R/S Configuration
With the lowest priority group (priority 4) oriented away from the viewer, the remaining three substituents trace a clockwise path from priority 1 to 2 to 3. This gives the R configuration.
