Alkene Reactions, part 3 (17 min)

This tutorial covers, catalytic hydrogenation and hydroboration-oxidation, two reactions that involve simultaneous addition of two groups to the pi bond of an alkene. (Runtime = 17:23)

Student Learning Outcomes
After viewing this tutorial and practicing problems from this website and your textbook, you should be able to:
• Understand enough of each mechanism to explain the stereochemical outcome of hydrogenation and hydroboration-oxidation reactions of alkenes.
• Know the differences between anti and syn addition to alkenes.
• Predict the major (and minor) products of hydrogenation and hydroboration-oxidation reactions of alkenes.

Practice Problems
Here are some problems to get you started. You should first try each on a piece of paper. Then, place your cursor over the graphic and click on right arrow that appears to see the answer. The right and left arrows allow you to move back and forth between problems. Please note that these are not the only types of problems/questions that exist on this topic. Refer to your textbook and any problems your instructor provides you for more practice with this subject.
