Complete the electron-pushing mechanism for the E1 reaction when
2-methylbutan-2-ol is treated with 20% sulfuric acid.
Hint: The E1 mechanism involves dissociation of the hydroxyl
group from the substrate. The acid is used to convert the hydroxyl
group to a good leaving group. Do not delete any pre-drawn
bonds/charges/lone pairs.
