Alkyne Reactions, part 2 (16 min)

This tutorial covers hydration reactions of alkynes (including the keto-enol tautomerization that follows hydration) and the use of acetylide ions in synthesis to form carbon-carbon bonds. (Runtime = 16:04)

Student Learning Outcomes
After viewing this tutorial and practicing problems from this website and your textbook, you should be able to:
• Predict the relative acidities of alkanes, alkenes, and alkynes.
• Predict the major (and minor) products of alkyne hydration reactions and understand why each gives a certain preferred regiochemical outcome.
• Understand the process of keto-enol tautomerization.
• Generate and use acetylide ions to form carbon-carbon bonds.

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.
