WebI have learnt that the absolute configuration of a chiral centre can be labelled as (R) or (S) according to the Cahn–Ingold–Prelog rules, when the hydrogen (or other lowest priority group) is facing backwards, i.e. going into into the page, and the remaining groups decrease in priority clockwise or anticlockwise respectively.On the other hand, if the hydrogen is … Websubstituent atoms attached to chiral centre are placed in an order of priority based upon their atomic numbers, with the ligand having the highest atomic number being assigned …
