- S.10. Describe the product formed as a result of the reaction between cyclohexanone and 3-butene-2-one by also writing down the mechanism of the reaction.Luminol, which is used by forensic scientists to find blood, fluoresces as a result of Diels–Alder-like process. The dianion of luminol reacts with O2 to form an unstable peroxide intermediate that then loses nitrogen to form a dicarboxylate and emit light. The process is similar to that in 14-21 and 14-22. Propose a mechanism for this process.Predict the reaction of methyl 3-oxocyclohexane-1-carboxylate with NaBH4/ h20 show the mechanism
- The nitroso group, −N=O, is one of the few nonhalogens that is an ortho- and para-directing deactivator. Explain this behaviour by drawing resonance structures of the carbocation intermediates in ortho, meta, and para electrophilic reaction onnitrosobenzene, C6H5−N=O.for each reaction give the expected substitution product and predict wether the mechanism will be first order (SN1) or second order (SN2) a) 2-chloro-2-methylbutane + CH3COOH b) isobutyl bromide + NaOMe c) 1-iodo-methylcyclohexane + CH3CH2OHI’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?
