Question

1. Assign R or S configuration on the chiral center(s) in each of the given molecule H =CH₂ сн,сня

Answer 1

solution: R- Referring Rectus he clock wise rotution, s- Sinister he antic lock wise rotution. Configuration: Spatical arrangement of the atoms of a chirul molecular entity and it's stereochemical description. Rule: 1) Highest atomic number first prioriti. proceed along the two 2) Two substituents with equul rank, substituent chain until there is a point of difference and then give highest atomic number first priority. 3) Put lowest priority substituent in the back ( dushed line) 4) Highest priority - in front ( wedged line) s) fro Proceed from 1 to 2 to 3 6) Determine direction, 7 clockwise - R - Anticlockwise-s If then lowest reverse priority group from * R to s above or the plane are front s to R.
