Question

I answered the following for this but it said part of it was wrong and gave me this feedback - what am I missing?

Water, not shown, is a byproduct of each reaction. Consequently, the reactants for each reaction must contain nine carbon atoms and three oxygen atoms (plus the associated hydrogen atoms).

Be sure that you have included the HH on the hydroxyl groups of the alcohols.

Note that each acetal group is part of a six-membered ring. Consequently, the alcohol must be a diol.

The reaction involves nucleophilic addition of the alcohol to the carbonyl group. Which reagent will increase the susceptibility of a carbonyl group to nucleophilic attack?

Propose syntheses of acetals A and B from carbonyl compounds and alcohols. Draw the structures of the carbonyl
compounds and the alcohols, and select the appropriate reaction conditions.
