Early organic chemists used the Hofmann elimination reaction as the last step of a process known as a Hofmann degradation—a method used to identify amines. In a Hofmann degradation, an amine is methylated with excess methyl iodide in a basic solution, treated with silver oxide to convert the quaternary ammonium iodide to a quaternary ammonium hydroxide, and then heated to allow it to undergo a Hofmann elimination. Once the alkene product is identified, working backward gives the structure of the amine. Identify the amine in each of the following cases: a. 4-Methyl-2-pentene is obtained from the Hofmann degradation of a primary amine. b. 3-Methyl-1-butene is obtained from the Hofmann degradation of a primary amine. c. 2-Methyl-1-3-butadiene is obtained from two successive Hofmann degradations of a secondary amine.

when methyl benzoate reacts with water in the presence of NaOH during saponification, provide the IUPAC of the carboxylate formed

In an attempt to synthesize compound C through a two-step process, a chemist discovered after completing the first step that they had inadvertently produced two distinct compounds, A and B. Upon examining the infrared spectroscopy (IR) results, it was observed that both A and B exhibited peaks indicative of a ketone and an ester group. Please provide the molecular structures of A and B. OEt NaOEt ΕΙΟ A B In a chemical experiment, they noticed that both components, A and B, from a combined sample turned into a new compound, C, during the following stage. The task is to determine what compound C looks like and explain how compound A or B changes into compound C through a reaction. Compound C should be the primary molecule containing carbon created in this process, not just a by-product. A B H3O+, H₂O, A Mechanism = с

4) Write the reaction between cyclohexanecarboxylic acid and thionyl chloride showing all three products (two gaseous and one liquid). Take the liquid product and treat it with 2 moles of dimethylamine in benzene as the solvent. You get two products. What are they? Draw their formulae and write their names.

Hydroxide acts as a nucleophile in protein degradation by hydrolysis of the peptide bond in water. Draw out an arrow pushing mechanism of the hydrolysis of a peptide bond. Identify the nucleophile and the electrophile in this reaction.

Prostaglandins are a class of cicosanoids, fatty acid derivatives with a variety of extremely potent actions on vertebrate tissues. They are responsible for producing fever and inflammation and its associated pain. Prostaglandins are derived from the 20- carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin endoperoxide synthase. This enzyme, a cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the immediate precursor of many different prostaglandins. Rate of formation of PGG2 with 10 mg/ml ibuprofen (mM/min) Arachidonic acid (mM) Rate of formation of PGG2 (mM/min) 0.190 12.3 0.228 13.9 0.342 17.5 0.570 1.33 22.2 28.8 7.71 8.88 11.9 16.3 24.0 The kinetic data given in the table are for the reaction catalyzed by a mutant of prostaglandin endoperoxide synthase. Focusing here on the first two columns, determine the Vmax and Km of the enzyme. Vmax = Km mM/min mM

Which of the following acid derivatives can be hydrolyzed in water spontaneously without acid or base catalysis? Benzamide Methyl benzoate Benzonitrile     Benzoyl chloride

Give the name of the product formed when hydrochloric acid is mixed with N,N-dimethyl-2-propanamine.

Write the structure of following organic compound

20:32 hydroxide 2. Using curved arrows, show the deprotonation mechanism of phenol with (OH). Also, provide the structure of the product of this deprotonation. Start answering this question by drawing the structure of phenol. Then hydroxide ion. Find your most reactive electrons and draw the curved arrow that shows where they would go to deprotonate phenol. Then "make a bond break a bond" write they question 3. Provide valid resonance structures for the product of the previous arrow(s) charge moving onto the ortho- and para positions. Use curved to show how the charge resonates to the next structure in your scheme. all the proper notations for depicting resonance. that show the in the structures Be sure to use Send a chat C
