Under milder temperatures than what is needed for dehydration, strong acids catalyze the self-condensation of 1-propyl alcohol to give di-n-propyl ether. The mechanism differs from that of today's reaction in that the protonated alcohol undergoes an Sn2 rather than an Sn1 reaction. Write the mechanism for the acid catalyzed condensation of ethyl alcohol to give diethyl ether. Make sure the mechanism includes protonation, Sn2, and deprotonation.
