- Consider the data below to answer the following questions. Cyanohydrins are important intermediates in the synthesis of a-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated.

The reaction of an aldehyde with hydrogen cyanide is an example of + NaCN + H₂O reaction. H- C. an electrophilic substitution d. a nucleophilic addition B. Identify the electrophile in the reaction of benzaldehyde with hydrogen cyanide.arrow_forwardRefer to the data below to answer the following questions: The octapeptide saralasin is a specific antagonist of angiotensin II. A derivative of saralasin is used therapeutically as an antihypertensive. Amino acid analysis of saralasin show the presence of the following amino acids: Ala, Arg, His, Pro, Sar, Tyr, Val, Val A. Sar is the abbreviation for sarcosine, N-methyl aminoethanoic acid. Draw the structure of sarcosine. B. N-Terminal analysis by the Edman method shows saralasin contains sarcosine at the N-terminus. Partial hydrolysis of saralasin with dilute hydrochloric acid yields the following fragments: Tyr-Val-His Sar-Arg-Val His-Pro-Ala Val-Tyr-Val Arg-Val-Tyr What is the structure of saralasin?arrow_forwardGive the major organic product(s) of each of the following reactions or sequences of reactions.
