- A synthetic organic molecule, G, which contains both aldehyde and ether functional groups, is subjected to a series of reactions in a multi-step synthesis pathway. In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group.

Ephedrine is one component ofa once-popular combination drug used by body builders to increaseenergy and alertness, whereas pseudoephedrine is a nasaldecongestant.a.) Draw the structure of naturally occurring (−)-ephedrine, which has the1R,2S configuration.b.) Draw the structure of naturally occurring (+)-pseudoephedrine, whichhas 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 stereogeniccenters.e.) How is each compound drawn in part (d) related to (−)-ephedrine?arrow_forwardProstaglandins are a class of eicosanoids, fatty acid derivatives involved in a variety of important phenomena, including fever, inflammation, and pain. The first step in prostaglandin synthesis involves the conversion of the 20-carbon fatty acid arachidonic acid to PGG2 by the enzyme prostaglandin endoperoxide synthase, or cyclooxy: Ibuprofen is one of several inhibitors of cyclooxogenase used therapeutically.

- Phenylethanol can be oxidised to phenylethanal or phenylethanoic acid, depending on the reagents used (both the alcohol and the aldehyde are of interest for their antimicrobial properties, while the acid is used to treat type II hyperammonemia): A (a) (b) (c) CoH,CH,CHO phenylethanal B C6H5CH₂CH₂OHC₂H₂CH₂CO₂H phenylethanol Suggest reagents (shown as A and B in the scheme above) that could be used to carry out the oxidation of the alcohol to the aldehyde and the acid, respectively. C6H5CH₂- Suggest two other syntheses of phenylethanoic acid, in each case indicating the starting materials and other reagents required, but not giving details of mechanism. One of your proposed syntheses must start with a compound which only contains seven carbon atoms (the acid product contains eight carbon atoms). phenylethanoic acid Phenylethanal can be converted to a hydrate in the presence of aqueous acid, though the position of equilibrium is very far to the left: H H+/H₂O OH C6H5CH₂-C-H OH Explain why…arrow_forward1.
