- Complete these reactions. (a) (b)arrow_forwardJj.168.arrow_forward5.57 The shrub ma huang (Section 5.4A) contains two biologically active stereoisomers-ephedrine and pseudoephedrine-with two stereogenic centers as shown in the given structure. Ephedrine is one component of a once-popular combination drug used by body builders to increase energy and alertness, whereas pseudoephedrine is a nasal decongestant. a. Draw the structure of naturally occurring (-)-ephedrine, which has the 1R,2S configuration. b. Draw the structure of naturally occurring (+)-pseudoephedrine, which has the 1S,2S configuration. c. How are ephedrine and pseudoephedrine related? d. Draw all other stereoisomers of (-)-ephedrine and (+)- pseudoephedrine, and give the R,S designation for all stereogenic centers. e. How is each compound drawn in part (d) related to (-)-ephedrine?arrow_forward

If the mixture was subjected to fractional distillation, how many fractions would be obtained? c. How many of these fractions would be optically active?arrow_forwardExplain why compound A is much more stable than compound B. A Barrow_forwardSeveral factors can affect alkene stability. Explain why alkene A is more stable than alkene B even though both contain disubstituted carbon–carbon double bonds.arrow_forward
