Question

Look at the reaction diagram for this reaction Figure 9.7 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 all halides react the fastest and primary alkyl haldes react the slowest with nucleophiles in this reaction Explain why this is consistent with the reaction diagram in fe 9.2. Stereochemistry of S2 and 51 Reactions The reaction shown is an 52 reaction a Mdid the curved rows in the reaction below and draw the transition state that forms refer to part of this sheet) b. Using mechanism and gure 91 in your textbook, what is the geometry around the reaction center in the transition state? Redraw the transition state from partaad the curved arrows and the final product that results [ ] - d. What has happened to the stereochemistry at the reaction center?

Note-  transition state does not follow rules of bonding, otherwise carbon would not have formed five bond (Sp3d hybridised state) in transition state. At normal condition carbon form maximum four bonds because of absence of sub-orbital. Transition state is formed at very high energy for very small time.
