Question

a) Look at the reaction diagram for this reaction (Figure 9.2 in your textbook) and answer the following questions. 1) Is this diagram consistent with the rate law? Why or why not? 2) Experimental evidence shows that tertiary alkyl halides react the fastest and primary alkyl halides react the slowest with nucleophiles in this reaction. Explain why this is consistent with the reaction diagram in fig. 9.2. Stereochemistry of S 2 and S1 Reactions 1. The reaction shown is an S2 reaction. a. Add the curved arrows in the reaction below and draw the transition state that forms (refer to part I of this sheet) сн, Но- + Br Br b. Using mechanism 9.1 and figure 9.1 in your textbook, what is the geometry around the reaction center in the transition state? c. Redraw the transition state from part a, add the curved arrows and the final product that results [ ] d. What has happened to the stereochemistry at the reaction center?
