A. Designate the R/S configuration for any chiral centers in the following molecules. B. H HN H 25. 1. 28. 4 22. 7. 16, 13. 19. 10 HO H Br HO HO HO 0. H Br H OH H Bri H CH3 H OH NH Answer key correct but Entor in movie for 16. H CH H OH H CH H CH HNH 20 H CH, H CH .H CI 2. 5. 8. 11. 14 20. 26 17. HCO H HN H OH H CH H OH H HO 23, HC NH H CH, H CH, OH H OH OH Answer key correct but Emer in movie for 20 NH HO H H CHOH NH LOH 29. This one is very hard. But for each of the 5 chiral C's, the tie-breaking processes do work. 12. 15. 18. HO 24. 21. H 27. H OH H OH 30. H CH, H OH Br, CH OH H CH, H H CHO H CHI
