(a) Propose a mechanism for the acid-catalyzed reaction of cyclohexanone with ethylene glycol to give cyclohexanone ethylene acetal.

(b) Propose a mechanism for the acid-catalyzed hydrolysis of cyclohexanone ethylene acetal.

(c) Compare the mechanisms you drew in parts (a) and (b). How similar are these mechanisms, comparing them in reverse order?

(d) Propose a mechanism for the acid-catalyzed hydrolysis of the acetal given in Problem 18-30(f).

Reference: Problem 18-30:

Show what alcohols and carbonyl compounds give the following derivatives.
