The acid-catalyzed dehydration of 2,2-dimethylcyclohexanol afforded 1,2dimethylcyclohexene. To explain this product we must use a mechanism for the reaction in which a methyl shift transforms a secondary carbocation into a tertiary one. A second product of the dehydration of 2,2-dimethylcyclohexanol is isopropylidenecyclopentane, shown in the equation. Write a stepwise mechanism \( \longrightarrow \) to rationalize its formation.
