Solution
1
Identify the reactant: The reactant is a dicarbonyl compound, which means it has two carbonyl groups (C=O) on a six-carbon chain
2
Predict the reaction type: The presence of water (H2O) and a hydroxide ion (OH-) suggests a base-catalyzed reaction, likely leading to the formation of a gem-diol
3
Write the reaction: The base (OH-) will attack one of the carbonyl carbons, forming a gem-diol intermediate. The reaction will proceed to form a stable 1,6-hexanediol product. The balanced chemical equation is: \text{O=C-(CH2)_4-C=O} + 2 \text{H2O} \rightarrow \text{HO-(CH2)_6-OH}
Answer
The reaction of the dicarbonyl compound with water in the presence of hydroxide ion yields 1,6-hexanediol.
Key Concept
Base-catalyzed hydration of a dicarbonyl compound
Explanation
In the presence of a base, a dicarbonyl compound reacts with water to form a gem-diol, which in this case is 1,6-hexanediol.
