A study guide on carbocation rearrangements View the blog post on this activity For an interactive experience, download the Mechanisms app from the Google Play or App store. For each of the following, find a more stable carbocation using a hydride and or alkyl shift and place your answer in the box if you've downloaded the pdf version of the guide, if not you can download it here. Use the space below the scheme to show your work. Then discover the answer by playing through the associated puzzle in Mechanisms. For more review on carbocation rearrangements watch the videos linked to the task card or view them under the puzzles below.

Looking for more practice? See if you can catch when a hydride shift and or an alkyl shift is a step in the following Mechanism puzzles: Substitution - 17, 18 Elimination - 17, 18, 20 Addition - 7, 9, 10, 17, 19, 20 Alcohol - 10, 11, 12
A interactive worksheet on Equilibrium View the blog post on this activity For an interactive experience, download the Mechanisms app from the Google Play or App store. For each of the following, play the puzzle in Mechanisms to identify the conjugate acid. Then decide if equilibrium favors the left or right side. (Refer to your textbook for pKa values.) Read the answer key to learn more about why it matters which side of the equilibrium is favored. A printable version of this worksheet is available here.
