The 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.
Account for the rapid rate of methanolysis of ClCH2OCH2CH3 even though the substrate is a primary halide. Hint: The reaction of the substrate with ethanol proceeds by SN1 mechanism. Draw the Lewisstructures.
(10pts) Compound A, C10H16, was found to be optically active. On catalytic reduction over a palladium catalyst, 2 equivalents of hydrogen were absorbed, yielding compound B, CioH2o. On ozonolysis of A, two fragments were obtained. One fragment was identified as acetic acid (CHCOOH). The other fragment, compound C, was an optically active carboxylic acid, C8H14O2. Write reactions, and draw the correct structures for A-C, explain your answer in detail.
Does the data provide evidence for the claim that the reaction of Br2 with alkenes proceeds via anti‐addition? YES OR NOW AND WHY The mleting point of the product was found to be 234.5-235.5C chemical reaction: trans-stilbene+pyrimindine tribromide --->acetic acid 1,2-di bromo-1,2-diphenylethane product was trans-1,2-dibromo-1,2-diphenylethane
Cembrene, C20H32, is a diterpenoid hydrocarbon isolated from pine resin. Cembrene has a UV absorption at 245 nm, but dihydrocembrene (C20H34), the product of hydrogenation with 1 equivalent of H2, has no UV absorption. On exhaustive hydrogenation, 4 equivalents of H2 react, and octahydrocembrene, C20H40, is produced. On ozonolysis of cembrene, followed by treatment of the ozonide with zinc, four carbonylcontaining products are obtained: Propose a structure for cembrene that is consistent with its formation from geranylgeranyl diphosphate.
Qa 18. Bromination of 5a-cholestan-3-one occurs at C-2 or C-4 to give 2 regioisomers. Two unsaturated ketones with lambdamax = 230 nm and lambdamax = 241 nm are yielded during dehydrobromination. Use Woodward-Fieser rules to distinguish between the two.
Explain this result: Acetic acid (CH3COOH), labeled at its OH oxygen with the uncommon 18O isotope (shown in red), was treated with aqueous base, and then the solution was acidified. Two products having the 18O label at different locations were formed.

Can someone explain the answers to 28, 29, and 30? The answers are B, A, A. I understand lindar catalyst makes cis alkenes and Na/NH3 makes trans alkenes but I dont understand how the second step of Br2, OsO4 influences the stereochemistry between the 2 . Will rate quickly if helpful. Thanks!
Which of A to E shows the likely product obtained from LiAlH4 reduction of the ketoamide shown below?
The rate constant for the uncatalyzed reaction of two molecules of glycine ethyl ester to form glycylglycine ethyl ester is 0.6 M- 1s - 1. In the presence of Co2 +, the rate constant is 1.5 * 106 M- 1s - 1. What rate enhancement does the catalyst provide?
