Practice Questions for Chapter 6 - CEM 251

Following are some sample mechanism questions from chapter 6. Keep in mind that the more time I spent discussing a mechanism in lecture, the more likely it is to appear on the exam!

Try drawing out answers to these problems and check your answers with each other and/or any of your instructors. Solutions to these problems will be available here approximately 1 week before the exam.

Draw the mechanism for the addition of HCl to 1-butyne. Refer to the mechanism to explain (in 10 words or less) the regioselectivity of the reaction.
Draw the mechanism for the addition of water to 1-propyne in the presence of acid. Refer to the mechanism to explain (in 10 words or less) the regioselectivity of the reaction.
