Does the data provide evidence for the claim that the reaction of Br2 with alkenes proceeds via anti‐addition? 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

I’m currently trying to write a lab report for the synthesis of dimolybdenum tetraacetate [Mo2(O2CCH3)4] from the reaction of molybdenum hexacarbonyl, Mo(CO)6 in glacial acetic acid and acetic anhydride under a nitrogen atmosphere, involving the difficult formation of a quadruple bond and requires high heat and long reaction time (approximately 20 hours). But these are the question I’m stumped on: 1. Why need the reaction be done under nitrogen? We also added dichlorobenzene and hexanes during the reaction. 2. Explain the purpose of dichlorobenzene and hexanes. 3. Why does the reaction take 20 hrs?
can i get help drawing out actual structures including the nucleophilic addition of Cy2NH to parafomaldehyde and its hemiaminal intermidiate and the condensation step when it is displaced by terminal alkyne forming allene, also what is dioxane getting rid of as the solvent, thanks
Calculate ΔSsys° (J/K) for the catalytic hydrogenation of acetylene to ethane: C2H2(g) + H2(g) → C2H4(g) Substance S° (J/K·mol) C2H2(g) 200.8 H2(g) 130.58 C2H4(g) 219.4
The incomplete hydrogenation of alkynes (E) using H2 (g) and Lindlar's catalyst may not always go smoothly. Excessive "poisoning" of the catalyst could prevent any hydrogenation, leading to the retrieval of the initial material (D). Conversely, insufficient "poisoning" may result in complete hydrogenation, yielding the alkane (F).Describe the analytical method(s) you would employ (such as IR, NMR, UV/VIS, etc...) and detail the specific information you would seek to confirm the existence or nonexistence of D, E, and F.

What reaction scheme would have - and electrophillic addition - the use of NaBH4 or LiAlH4 - a reaction that generates a new stereocentre - 2-methylbutan-1-ol
An unknown hydrocarbon G, whose formula is C16H26 contains two triple bonds. Ozonolysis followed by reduction with (CH3)2S gave CH3(CH2)4CO2H and HO2CCH2CH2CO2H as the only products. Suggest a reasonable structure for compound G.
Match the heats of hydrogenation (107 kJ/mol, 114.5 kJ/mol, and 119 kJ/mol) with the appropriate C7H12 isomer.
When 2-methylpropane is monochlorinated in the presence of light at room temperature, 36% of the product is 2-chloro-2-methylpropane and 64% is 1-chloro-2-methylpropane. From these data, calculate how much easier it is to remove a hydrogen atom from a tertiary carbon than from a primary carbon under these conditions.
Uemura and coworkers studied a time dependent Diels-Alder reaction which first formed the endo product as the major organic product and with time produced the exo product (J. Org. Chem. 2018, 83, 9300−9304). Show the endo and exo product for the reaction below. Which is the thermodynamic product and which is the kinetic product? Explain your reasoning.
