The molecule in the next column is 2,2 -dimethylpropan-1-ol, a primary alcohol. Because no H atoms are bonded to the carbon atom in this molecule, dehydration seems unlikely. However, when 2,2-dimethylpropan-1-ol is heated with an acid catalyst, 2-methylbut-2-ene is obtained. Suggest a mechanism that shows how 2 -methylbut-2-ene is formed. [Hint: Consider the formation and rearrangement of a carbocation. See Are You Wondering 27-2.]
