WebNov 24, 2015 · The highest to lowest priority is (1,2,3,4): tertiary amine (highest atomic number here; −NC2) aromatic sp2 (taken similar to tert-butyl, i.e. −CC3) methylene ( −CH2) hydride ( −H) You get that from going clockwise and crossing the hydride, but since the hydride is facing forwards rather than backwards, the configuration is the reverse ... WebAug 31, 2024 · To determine whether the chirality center is R or S you have to first prioritize all four groups connected to the chirality center. Then, rotate the molecule so that the fourth priority group is on a dash (pointing away from you). Finally, determine whether the sequence 1-2-3 is (R) clockwise or (S) counterclockwise.
