Question

I just need the potential side reaction that will occur. The reaction creating the products (2-methyl-1-butene and 2-methyl-2-butene) is between 2-methyl-2-butanol and sulfuric acid. I already have the arrow pushing mechanism I just do not know what the potential, undesired side product is. Please show the mechanism.

Describe and provide a detailed mechanism (use arrow pushing) for the preparation of 2-methyl- 1-butene and 2-methyl-2-butene. 2 pts Provide a potential undesired (side) reaction that can occur during the preparation of the alkenes. 2 pts
