Question

Assign R, S configurations to each indicated chirality center in the molecules below. B. COOH A. OH HOW -H CHANH HNCH HO norepinephrine alamine HOC / OH CH3 не HC HÓ COH tartaric acid CH2 dihadrocarpone

Answer 1

HO3AH Jockwise = R configuration. HO ,C004 Brch MH. clockwise but lowest priority is not on dashed line =S contiguration. Hoe om OH H clockwise - R contiguration. Oon E carbon Il Ich for D carbon anticlockwise but lowest priority group is on the above the plane = 5 contiguration. for E carbon anticlockwise rotations configuration.
know the answer then explanation is given below

the configuration at the Carbon atoms (a) is R configuration.

the configuration at the Carbon atom (b) is S configuration.

The configuration at the Carbon atom (c) is R configuration.

The configuration at the Carbon atom (d) is S configuration.

The configuration at the Carbon atom (e) is S configuration.

To assign R and S configuration - in the given compund having based and solid lines. The first step is to prioritize group around chiral Carbon by CIP rule.

In the next step.

if lowest priority group is on dashed line, then for clockwise rotation assign R configuration. And for Anticlockwise rotation assign S configuration.

if the lowest priority group is not on the dashed line , for clockwise rotation assign the S configuration and for Anticlockwise rotation assign the R configuration.
