Unformatted text preview: 3 pts The more stable, more substituted alkene (Saytzeff) is formed from the more stable, more substituted (3 o from rearrangement) carbocation. 3. (15 points) Consider the following S N 2 reaction. HO + + CH 3 Br Br CH 3 OH a) Draw in the curved arrows that show the electron flow from reactants to products above. 6 pts b) Given that the reaction is exothermic, sketch a reaction vs energy diagram. Label the reactants and products. Draw the structure of the rate limiting transition state at the appropriate location on your diagram . Be careful to illustrate clearly the geometry around the carbon atom. For full credit, be sure to show whether or not the transition state is reactant-like or product-like, by indicating which of the two partial bonds is longer. 9 pts CH 3 Br + OH-CH 3 OH + Br-Energy Reaction C H H H HO Br...
