Expert Solution
Step 1
R/S nomenclature is based on CIP rule which states that higher is the atomic number of directly attached atom, higher will be the priority.
When 4th group is vertical : 1 to 2 to 3 clockwise rotation R and anti-clockwise rotation S.
When 4th group is horizontal : 1 to 2 to 3 clockwise rotation S and anti-clockwise rotation R.
