This reaction does not follow the expected theory. Given what you know about substitution/elimination, what is the expected mechanism this reaction should follow? Suggest why that is not what happens and give the actual product of the reaction. Br ткон s

c. Snl reactions dominate under polar protic solvents. Increasing the polarity of the solvent will increase the rate of the reaction because the polar solvent will stabilize the dispersed charges on the transition state more than it will stabilize the neutral reactant.

SN1 reactions are better performed in protic solvents. Explain why the researchers could not perform the reaction using 100% water as solvent instead of 50% aqueous acetone.

Br tBuO H3C H3C CH2 H2 Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found alkyl halide the reaction is second order. The substitution reaction is thus termed SN2, and the elimination reaction is be dependent upon the concentration of the nucleophile as well as the termed E2. These reactions are bimolecular and take place in a single step. In the SN2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsev's rule whereby the more substituted alkene is generally formed. In E2 elimination, both the B-hydrogen and the leaving group must be oriented anti to each other. The same reaction…

Sn1 reaction in five sentences or less discuss how your product mixture is separated from all reactant and byproducts starting with the desired products and four other components present in the mixture. Begin by indicating how the first component is separated from the others and how the solubility of one compound versus the others in the solvent played a major role in this separation.
