Answer ALL parts of this question. Fluoxetine (Prozac) is an anti-depressant, sold as a racemic mixture with both enantiomers of equal activity. (S)-Fluoxetine has a specific optical rotation of +14.0°. F₂C. HO (S)-Fluoxetine (c) A laboratory mixture has 80% enantiomeric excess (ee) of (S)-fluoxetine. What percentage of each enantiomer is present in the mixture? (d) What is the observed specific rotation of the laboratory mixture in part (c)? (e) Draw the product of HCI reaction with (S)-fluoxetine.

Why does the melting point (70-71) above match neither the enantiomers’ nor the racemate’s? Does it mean that the substance is impure, or perhaps isn’t even ibuprofen at all? (Racemic mixture:75-77C, Enantiomer:52-53C)

Please help me how to solve this problem in detail so i can understand it. Thank you very much.

please answer all parts , thank you :)

Name the compounds shown below. Use an R of an S to label each chirality center

Q8. Draw the two possible chair-like conformations of compound 1. 2 Using the Cahn Ingold Prelog priority rules, assign the absolute stereochemistry to each stereogenic centre contained in compound 1. NH2 1

When oxaloacetic acid and acetyl-coenzyme A (acetyl-CoA) labeled with radioactive carbon-14 in position 2 are incubated with citrate synthase, an enzyme of the tricarboxylic acid cycle, only the following enantiomer of [2-14C]citric acid is formed stereoselectively. Note that citric acid containing only 12C is achiral. Assign an R or S configuration to this enantiomer of [2-14C]citric acid. (Note: Carbon-14 has a higher priority than carbon-12.)
