QUESTION 6 6) Select a FALSE statement about the SN2 & E2 mechanisms for the reaction between an Alkyl Halide (RX) reactant and an anionic reagent that could act as Nucleophile (Nu") or Bronsted Base (B): A) There is NO involvement of reactive intermediates in either mechanism. B) E2 mechanism involves simultaneous loss of the halide and loss of a B-proton in one step C) SN2 mechanism involves stereospecific attack of nucleophile from the opposite side of the leaving group D) Both mechanisms have the SAME type of rate equation rate = k [RX] 4 O A OB ос OD 2 pa 2

[Review Topics] [References] Acyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. H3C CH3 H2O NaOH • You do not have to consider stereochemistry. • Include all valence lone pairs in your answer. • Do not include counter-ions, e.g., Nat, I', in your answer. • In cases where there is more than one answer, just draw one.
