For the following reactions, write the predominant product(s) in the space provided, then in the box above the arrow write the predominant mechanism of the reaction. Make sure to indicate stereochemistry with wedges and dashes as appropriate.

Watch Solution

Draw the predominant product expected for each of the following E2 reactions.

Watch Solution

For the following E2 reaction, draw the transition state that leads to the predominant product(s), indicating geometry and stereochemistry with wedges and dashes. We will be paying particular attention to the geometry of your transition state. No need to show any arrows for moving electrons here, we are just interested in the transistion state and product structures. In your transition state structure, be sure to show bonds being made or broken as dotted lines
