- Show how to bring about each step in this synthesis of the herbicide propranil.arrow_forwardThe formation of Br2 from NBS first involves the reaction of NBS with HBr to form an iminol intermediate and molecular bromine. The intermediate then undergoes acid-catalyzed tautomerism to form succinimide, the byproduct of the reaction. Propose a curved-arrow mechanism for the conversion of NBS into succinimide that also accounts for the formation of Br2.arrow_forwardMethyl benzoate was exposed to a nitration test, although it was difficult to see the formation of a fragrant yellow solution. What produced this consequence?arrow_forward
- What is a major difference between acid and base catalyzed hydration of a carbonyl? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a A base deprotonates water, and an acid protonates the carbonyl in the first step of the mechanism. b A base deprotonates water, and an acid protonates the alkoxide in the second step of the mechanism. с A base deprotonates the carbonyl, and an acid protonates water in the first step of the mechanism. d A base deprotonates the carbonyl, and an acid protonates water in the second step of the mechanism.arrow_forwardDraw the structure(s) of the organic product(s) predicted when this compound reacts with KCN, HCN.arrow_forwardTollen’s reagent reacts with acetic acid which leads to the formation of silver precipitate. Explain the molecular basis.arrow_forward
- ● Give three examples of how elimination reactions are used in drug synthesisarrow_forward6. The reaction between aniline and nitrous acid at low temperature yields A) an N-nitroso amine B) a diazonium salt C) a nitrile D) an amine nitrite salt 7. An organic nitrogen compound, X, gives ammonia on warming with dilute aqueous sodium hydroxide, X could be A) ethanamide B) ethylamine C) phenylamine D) amino ethanoic acidarrow_forwardThe reaction that occurs when the benzaldehyde you have is reacted in a basic environment is called the Cannizzaro reaction, and when it is reacted with cyanide, it is called benzoin. It Explain the reason by writing the reaction mechanisms of the reactions.arrow_forward
- Why do you wash the dichloromethane solution of your reductive amination product with sodium bicarbonate, rather than dilute aqueous HCl? a) Sodium bicarbonate is a good method of removing aldehydes from organic solvent.b) The amine product will be protonated by acid and remain in the aqueous layer as a salt.c) Sodium bicarbonate transfers the amine starting material into the aqueous layer.d) Sodium bicarbonate reacts with leftover NaBH(OAc)3 and removes it from the mixture.arrow_forwardWhich of the following statements is correct? A. The haloform reaction proceeds under very difficult conditions and the yield is very low. B. The haloform reaction is used only for the identification of compounds containing secondary alcohol groups. C. Methyl ketones or alcohols are oxidized by halogens in acidic solutions to give carboxylic acids and the corresponding haloform product. D. Enolate anions react rapidly with halogens to give alpha-halocarbonyl compounds.arrow_forwardThe substance provided can be prepared by a nucleophilic addition reaction between an aldehydeor ketone and nucleophile. Identify the reactants from which it was prepared. If the substance is an acetal, identify the carbonyl compound and the alcohol; if it is an imine or enamine, identify the carbonyl compound and the amine.arrow_forward
