Acid-Catalyzed Dehydration of Alcohols

Problem # 519

Let's work through an elimination reaction. Draw the structures for each of the species in the three boxes below (protonated thiol, carbocation, and alkene). Also draw curved arrows to show electron movement. 

Problem # 348

For the reaction below, draw the structures of the carbocation intermediate and the final product.

Problem # 341

 Predict the product(s) of the reaction below, and used curved arrows to show a mechanism.

Problem # 333

Let's go over how a carbocation can form from an alcohol.

Write in the curved arrows to show the formation of the protonated alcohol, and water acting as a leaving group to form a carbocation.
