- Explain how and why rearrangements occurduring Friedel-Crafts alkylation reactions formingmore than 1 product. Also illustrate therearrangement reaction from the aboveexample.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?The reaction of an organic acid with an alcohol, inorganic solvent, to produce an ester and water is commonlydone in the pharmaceutical industry. This reactionis catalyzed by strong acid (usually H2SO4). A simpleexample is the reaction of acetic acid with ethyl alcoholto produce ethyl acetate and water: CH3COOH(solv) + CH3CH2OH(solv) ⇌ CH3COOCH2CH3(solv) + H2O(solv) where “(solv)” indicates that all reactants and products arein solution but not an aqueous solution. The equilibriumconstant for this reaction at 55 °C is 6.68. A pharmaceuticalchemist makes up 15.0 L of a solution that is initially0.275 M in acetic acid and 3.85 M in ethanol. At equilibrium,how many grams of ethyl acetate are formed?
