Chirality priority
WebAug 11, 2015 · The Cahn-Ingold-Prelog sequence rules assign priorities to the groups attached to each chiral centre. The atom with higher atomic number receives higher priority. If there is a tie, we go one bond further out until we come to the earliest difference. If there is still a tie, we keep going further out until we find a difference.

WebAug 22, 2024 · Chiral center: Chiral center is an atom bonded tetrahedrally to four different groups or atoms called ligands. Chiral center usually C atom but may be N, S, P, Si etc. In organic compounds, chiral center is an asymmetric tetrahedral carbon atom that is bonded with four different groups. Chiral molecules have two enantiomers and at least one ... WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).

I am trying to figure out the configuration for this chiral carbon to answer a homework question, however they arbitrarily include a "D" group as shown in the image. My guess is that it is some higher priority group than the carbon, and lower priority than the halide, making the configuration (S). Is this correct? the piggott times newspaper
