C) D) please
2-bromobutane will react with^-OCH_3 in the present of dimethylsulfoxide, DMSO, as a solvent to create 1-butene and 2-butene by an elimination reaction. Write the chemical equation showing the structural formulas of all reactants and products. How does this mechanism occur? Circle either E1 or E2 Draw the energy diagram for the desired mechanism. Be sure to label activation energies, transition states, energy levels of reactants and products, change of enthalphy, any intermediate (if it exist). Show how...

11. For each of the following reactions, predict whether Syl or Sy2 will be the primary substitution mechanism. (Circle one) Br Nal in H2O - SN or SN2 CH,OH Sn1 or SN2 NaCN in DMSO Sn1 or S2 12. For the second reaction in question 11 (above), which do you think would react faster--the sec- ondary bromide or a secondary chloride (assuming the same reaction conditions)? (Circle one) Bromide Chloride Neither (rates are the same)
