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?

Useful Information: sodium metam: Commercial grade sodium metam is 33% pure sodium metam by weight and has a density of 1.2 g/mL. Hydrolysis of metam (Methyl isothiocynate) + H2S Rate constants for hydrolysis for metam (base catalyzed hydrolysis is negligible) = 300 mol -1 L. sec -1 , = 1 x 10-8 sec-1 Metam also undergoes photolysis to methyl isothiocyanate with a half-life of 1.6 hrs. Data for Sacramento River discharge Q = 75,000 L/min mean depth = 0.30 m pH = 7.8 mean width = 3.2 m dispersion coefficient D = 1.6 x 102 m2/min Assuming the spill acts acts as a single point source.

The second-order rate constants for the reaction of oxygen atoms with aromatic hydrocarbons have been measured (R. Atkinson and J.N. Pitts, J. Phys. Chem. 79, 295 (1975)). In the reaction with benzene the rate constants are 1.44 × 107 dm3 mol−1 s−1 at 300.3 K, 3.03 × 107 dm3 mol−1 s−1 at 341.2 K, and 6.9 × 107 dm3 mol−1 s−1 at 392.2 K. Find the frequency factor and activation energy of the reaction.

. Highlight all the safety features mentioned. Is this reaction more dangerous than most reactions? 4,4'-DIBROMOBIPHENYL Robert E. Buckles and Norris G. Wheeler1. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The resulting crystals are filtered, giving a…
