The configuration of (+)-benzylmethylphenylphosphine is S is to be verified. Concept introduction: In order to determine the configuration at a chiral center, the atoms or groups attached to it are first assigned priorities on the basis of their atomic numbers . If two atoms attached to the chiral center have the same atomic number, then they are compared on the basis of the atomic numbers of the other atoms attached to them. Multiple bonds are replicated as substituents on the atom. The molecule is oriented such that the lowest ranked group/atom points away from the observer. The configuration is R, if the remaining three groups in the order of decreasing priority trace a clockwise path. The absolute configuration is S, if the remaining three groups in the order of decreasing priority trace a counter clockwise path.
