Acid-catalyzed dehydration of 3,3-dimethyl-2-butanol yields two compounds A and B, each having a molecular formula C6H12. The 1 H NMR of compound A shows a single peak at d = 1.64 ppm whereas the 1 H NMR of B has more than one peak. Suggest structures for compounds A and B and write a reasonable curved arrow mechanism for the formation of each.
