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.
