Propose the mechanism and product(s) for the following substitution reaction.arrow_forwardA chemist needs an ether to use as a solvent for a reaction and wants to synthesize it in one step from two of the following available reagents: sodium ethoxide, bromomethane, potassium tert-butoxide, and 2-bromo-2-methylpropane. i) Which combination(s) will give a good yield of an ether? Illustrate, showing the mechanism of the reaction. ii) Illustrate with a mechanism the reaction of one of the combinations that will not yield an ether?arrow_forwardOH NaOH H3C CH3 H3C CH3 Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed Sy1, and the elimination reaction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss of the leaving group to form a carbocation. In the second, fast, step the nucleophile adds to the carbocation in the SN1 reaction or elimination occurs to give an alkene in the E1 reaction. Because the carbocation is planar, the nucleophile can add to either face and therefore racemization is usually observed although solvent effects can influence this somewhat. E1 elimination follows Zaitsev's rule and typically yields the most substituted alkene as the major product. Conditions which favor the Sy1/E1 pathway include…arrow_forward
