1. When you have a carbocation in a reaction mechanism, why can the nucleophile add to different sides? (Note: this has to do with stereochemistry). 2. In your own words, explain what the term regiochemistry means as it applies to a reaction. 3. In your own words, explain what the term stereochemistry means as it applies to a reaction. 4. What is the official name of the "rule" that tells us that we get the more substituted product in an addition reaction? 5. Try to draw in the major product (note we mean the Markovnikov product) of the reaction shown. For the following questions, use the reaction below to answer them. 6. Give the major product (fill in the blank). 7. Fill in the arrows for the first step of the mechanism. (1 helped a little bit here). H 8. Why is the positive charge on carbon 2 and not carbon 1 ? Why isn't it on carbon 3 or 4 ? 9. What is the last step of the mechanism? (Fill in the arrows in the diagram above). 10. There are two phrases that we normally look for in an addition reaction mechanism. One explains the regiochemistry and the second explains the stereochemistry. What are the two phrases that would accompany this mechanism? 11. How many steps are in the mechanism of the addition of water to a double bond, and how many involve the catalyst? 12. What is the first step of the mechanism of the acid catalyzed addition of water to a double bond? (hint: think about what the nucleophile is)... have helped a little bit here by drawing in the protonated water. 13. Which carbon will have the charge in the carbocation intermediate from the step above? 14. Why is this the preferred carbocation? 15. What is the second step of the mechanism? Try to draw it in the space below. 16. The last step is the reformation of the catalyst/ deprotonation of the intermediate. I have filled in part of the steps, try to add the arrows
