R and s. Absolute Configuration: R-S Sequence Rules

Absolute configuration uses a set of rules to describe the relative positions of each bond around the chiral center atom. The lowest priority group is pointing and therefore, the clockwise direction of the arrow indicates an R configuration. Multi Point Fuel Injection. The other enantiomer, of course, must have the S configuration. In this section the lower priority group is in the planeit should be below the plane. Despite the tremendous and unique impact on access to molecular structures, X-ray crystallography poses some challenges. It rapidly inverts its configuration equilibrium arrows by passing through a planar, sp 2 -hybridized transition state, leading to a mixture of interconverting R and S configurations.
