Suggest an explanation for this result, based on an analysis of the inductive and resonance electronic effects of the two substituents on the stability of theWheland intermediate for para substitution by an electrophile E+
- Provide the major organic product(s) of the reactions below.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?give reactions and intima mechanism of following reactions-
- in terms of ortho/para and meta directors, give the major products formed and indictae why Please Answer all the parts otherwise I'll downvoteAn inexperienced graduate student treated dec-5-ene with borane in THF, placed the flask in a refrigerator, and left for aparty. When he returned from the party, he discovered that the refrigerator was broken and that it had gotten quite warminside. Although all the THF had evaporated from the flask, he treated the residue with basic hydrogen peroxide. Tohis surprise, he recovered a fair yield of decan-1-ol. Use a mechanism to show how this reaction might have occurred.(Hint: The addition of BH3 is reversible.)Organotin compounds play a significant role in diverse industrial applications.
