R-S Configuration and Configurational Isomers

R-S Configuration R-S Configuration its helps identify Enantiomers and Diatereomers Enantiomer:- Non superimposed mirror image Diatereomer:- Non superimposable , Non mirror image (R,R SR or SS RS ) R = Clock wise when counting A/c to CIP Rule S = Anti Clock wish CIP Rule For R-S 1 Higher the atomic Number & Higher the priority 2 Higher isotope preferred then lighter 3 IF first attack atom are same so move toward next 4 Multiple bond are solved A/c to their multiplicity 5 Lone pair e- get lowest preference than H 6 When lighter atom desh then counting No. Clock wise so R and Anti clock wise so S 7 When ligher atom wedge then counting No.Clock wise R = S each opposite
