Options
- A(2R, 3R)
- B(2R, 3S)
- C(2S, 3R)
- D(2S, 3S)
Correct answer
C. (2S, 3R)
Step-by-step solution
For 2nd carbon the priority order a > b > c > d a = - O H b = - C H - | C l C H 3 c = - C O 2 H d = - H For 3rd carbon the priority order a ′ > b ′ > c ′ > d ′ a ′ = - C l b ′ = - C H - | O H C O 2 H c ′ = - C H 3 d ′ = - H
