Unformatted text preview: electrons, and be sure to draw structures of all important reaction intermediates. If a reaction intermediate is a resonance hybrid, it is only necessary to draw the most important contributing resonance structure. You may assume that the hydronium ion, H 3 O+, is the acidic species that will react with the acetal. You do not need to show how H 3 O + is formed. (Hint : Remember that the mechanism of acetal formation that we discussed in lecture is reversible.)...
