- Why does the final product has the opposite configuration compared to the reactant? Shouldn’t it form OMs first, then OMs gets substituted by Cl- via Sn2 (the 1st inversion of configuration) then the Cl- gets substituted by OCH3- (the 2nd inversion of configuration? To my understanding 2 inversions = same configurationIn the beginning of this video https://www.youtube.com/watch?v=9Ng6Zv9oLzk, what reason is given on why the dienophile likes the diene?what is the major product of the SN1 OR SN2 structure below?
- Which of the following substances in each per will be the most reactive in SN1 reactions? justifyArrange the alkyl halides in order of increasing reactivity in an SN2 reaction with KI in acetone (least first). I, IV, III, II II, III, I, IV IV, I, III, II III, II, IV, IOrganotin 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?
