Peptides may be synthesized using an α-keto acid and a hydroxylamine. Concept introduction: The reaction of formation of an amide/ peptide from an α-keto acid and a hydroxylamine involves an initial nucleophilic substitution of the alkyl group to the keto group followed by decarboxylation and elimination of water molecule. To determine: Mechanism of reaction thought to occur by nucleophilic addition of the N-alkylhydroxylamine to the keto acid as if forming an oxime.

Question

A 0.552-g sample of an unknown acid was dissolved in water to a total volume of 20.0 mL. This sample was titrated with 0.1103 M KOH. The equivalence point occurred at 29.42 mL base added. The pH of the solution at 10.0 mL base added was 3.72. Determine the molar mass of the acid. Determine the Ka of the acid.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will its major product: 2,0° with a new C-C bond as If this reaction will work, draw the major organic product or products you would expect in the drawing aree below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and desh bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C-C bond, just check the box under the drawing area and leave it blank.
