Determine the R/S orientation of the indicated chiral center(s) in the following molecules. If there is only one chiral center in the molecule, choose (none). Molecule #1 ( sobrerol ): Center a: _______ Center b: _______ Molecule #2 ( pulegone ): Center a: _______ Center b: _______

Respuesta :

Answer:

Molecule #1 ( sobrerol )

Center a: R

Center b: S

Molecule #2 ( pulegone )

Center a: none

Center b: R

Explanation:

The lowest priority group is curved the clockwise configuration of molecule is referred to as S and anti clockwise configuration is R. The absolute configuration of chiral center is defined by Cahn-ingold-Prelog rules. The sobrerol has center a as R configuration and center b as S configuration. The center a configuration of pulegone is none.
