Question

can A B C be answrred and labeled please

2. The shrub ma huang oontains two biologically active stereoisomers-ephedrine and pseudoephedrine-with two stereogenic carbon atoms. Ephedrine is one component of a once popular combination drug used by body builders to increase energy and alertness, while pseudoephedrine is a newsworthy nasal decongestant. The IUPAC name of (-) ephedrine is (1R, 2S)-2-(methylamino)-1-phenyl-1-propanol. OH -NHCH a. Build a model of (-) ephedrine, which has the 1R,2S configuration. b. Draw the structure of (-) ephedrine using line-bond drawings. c. Draw a Newman projection of the staggered conformation of ephedrine looking down the C1-C2 bond. d. Go back to b and c, and draw the mirror images of the structures you drew.

Answer 1

pH – NH CH3 any stereoisomer. Strategy is at first you draw then change it you need to like - OH a here we got the IR,25 isomer in first attente ph ab NHCHR 8 HO RH | Cà MH -- 14 S'' 3 just draw the corresponding fisher. u bh 1 INC. y Hot HOUX } Belipsed form this is the staggered conformation
