The chirality … Webpriority group at back) i.e. (S)-(-)-serine It is important to practice and make sure you are comfortable at assigning (R) and (S) configurations to stereogenic centres. As an exercise, assign the configurations of all the chiral molecules containing a single stereogenic centre shown on page 3 of the lecture 1 handout. NB.

WebIn order to assign the configuration as R- or S- : Identify each of the chirality centers (most commonly an sp 3 C with 4 different groups attached) Then at each chirality center.... Assign the priority (high = 1 to low = 4) to each group attached to the chirality center based on atomic number. WebIn this instance, he is trying to assign priority based on the what carbons 1 and 3 are bonded to, not the rest of the molecule. The carbon above the chirality center (carbon 1) does not have 2 oxygens bonded to it but you count it as 2 because of the pi bond when assigning absolute configuration.
