Alkyne Reactions, part 1 (16 min)

This tutorial covers, hydrohalogenation, halogenation, and hydrogenation, stoichiometrically controllable reactions of alkynes. (Runtime = 16:12)

Student Learning Outcomes
After viewing this tutorial and practicing problems from this website and your textbook, you should be able to:
• Draw the mechanism of any hydrohalogenation, halogenation, or dissolving metal reduction reaction of an alkyne.
• Understand how stoichiometry (i.e., number of equivalents of your reagents) can be used to control some, but not all, reactions of alkynes.
• Predict the major (and minor) products of alkyne hydrohalogenation, halogenation, and hydrogenation reactions.

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.
