- Organotin compounds play a significant role in diverse industrial applications. They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(CzHs)3). 3SnCl4 + 4Al(C2H5)3 → 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.160 L of SnCl4 (d= 2.226 g/mL) was treated with 0.346 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL). What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)? If 0.257L of tetraethylstannane (d= 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?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?Organotin compounds play a significant role in diverse industrial applications.

- The reaction of 1-iodopropane with potassium thiocyanate (KSCN) in certain solvents results in the formation of two isomeric products, propylthiocyanate and propylisothiocyanate (see scheme below), via the SN2 reaction mechanism. Attempts to prepare a similar mixture of these same isomeric products (propylthiocyanate and propylisothiocyanate) starting from 1-propene is illustrated below. Despite the strong acidity of thiocyanic acid (recall pKa = 1.1), this addition reaction does not lead to either of the products indicated. Based on your knowledge of alkene addition reactions, explain this experimental result.Chemistry Give the products of the reaction of 1 mole of 2-methy1-1,3-pentadiene with 1 mole of HBr.
