Solution: For the following dehydration:A. Predict the product of the following reaction.B. Construct a reaction mechanism that accounts for the product proposed.C. Construct a reaction coordinate diagram for the reaction. Label all axes. Note that the reaction has three steps: The 1st is fast and endothermic. The 2nd is slow and endothermic. The 3rd is fast and exothermic. The overall reaction is exothermic.D. Using complete sentences state how you have shown that the 1st and 3rd steps are fast and that the 2nd reaction is slow.

Problem

For the following dehydration:

A. Predict the product of the following reaction.

B. Construct a reaction mechanism that accounts for the product proposed.

C. Construct a reaction coordinate diagram for the reaction. Label all axes. Note that the reaction has three steps: The 1st is fast and endothermic. The 2nd is slow and endothermic. The 3rd is fast and exothermic. The overall reaction is exothermic.

D. Using complete sentences state how you have shown that the 1st and 3rd steps are fast and that the 2nd reaction is slow.
