Answer
Explanation:
Step1: Determine priorities for molecule I
Assign priorities to groups attached to chiral - carbon based on atomic number. F (highest atomic number) > ethyl > methyl > H. When the lowest - priority group (H) is facing away, the direction of the remaining groups is clock - wise, so it is R.
Step2: Determine priorities for molecule II
For molecule II, OH (highest priority due to O) > ethyl > methyl > H. When the lowest - priority group (H) is facing away, the direction of the remaining groups is counter - clockwise, so it is S.
Answer:
B. R, S
