Chapter 10, Problem 10.60P

Less stable alkenes can be isomerized to more stable alkenes by treatment with strong acid. For example,

$2,3-\text{dimethy lbut}-1-\text{ene}$ is converted to $2,3-\text{dimethylbut}-2-\text{ene}$ when treated with ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$. Draw a

stepwise mechanism for this isomerization process.
