The structure of ( S , S ) − ethambutol is to be drawn. Concept introduction: A carbon atom that has four nonequivalent atoms or groups attached to it is known as chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers. The naming of chiral center and geometric isomers are based on Cahn-Ingold-Prelog priority rules. If the priority assigned to each group attached to the chirality center in a molecule is in a clockwise direction, then it is the R -stereoisomer, and if this is counter-clockwise, then it is the S -stereoisomer. R and S -stereoisomer are mirror images of each other.
