Practice Problem 11.11

An exception to what is stated above has to do with syntheses of unsymmetrical ethers in which one alkyl group is a tert-butyl group and the other group is primary. For example, this synthesis can be accomplished by adding tm-butyl alcohol to a mixture of the primary alcohol and $H_{2}S{O}_4$ at room temperature.

Give a likely mechanism for this reaction and explain why it is successful.
