2-Bromo-2-methylbutane undergoes an E1 elimination reaction in the presence of ethanol. In the next reaction only one of the possible products is represented. Although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. Complete the mechanism and draw the missing substances. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with bonds, including charges where needed....
Gradescope 3 This question is worth 8 points. Subdivide one box on your answer sheet into 2 smaller boxes. Label these smaller boxes and For each of the following structures, (1) draw the structure given (2) draw a reasonable resonance structure, (3) use curved arrows to show the flow of electrons for the formation of the resonance structure, and (4) label the resonance structure that is the largest contributor to the resonance hybrid (the major contributor), and briefly explain why....
On standing, 2-bromo-3-methylbutane is converted into 2-bromo-2-methytbutane. Propose a curved-arrow mechanism for this transformation. The reaction of butylamine, CH_3(CH_2)NH_2, with 1-bromoethane in 60% aqueous ethanol follows the rate law Rate = k[butylamine][1-bromobutane] The product of the reaction is (CH_3CH_2CH_2CH_2)_2NH_2-Br^-. The following very similar reaction, however, has a first order rate law: Give a mechanism for each reaction that is consistent with its rate law and with other facts about nucleophilic substitution reactions. Use the curved-arrow formalism.
