Question

In acid-catalyzed addition of water to a carbonyl group, what are the order of events?

Answer 1

The order of events in acid-catalyzed addition of water to a carbonyl group includes nucleophilic attack, proton transfer, and deprotonation.

Step-by-step explanation:

The order of events in acid-catalyzed addition of water to a carbonyl group can be summarized as follows:

1. The carbonyl group undergoes nucleophilic attack by water, resulting in the formation of a tetrahedral intermediate.
2. An acidic proton, typically from the acid catalyst, is transferred to the oxygen atom of the tetrahedral intermediate, leading to the formation of a carbonyl group and a hydronium ion.
3. The hydronium ion then deprotonates the carbonyl oxygen, generating an alcohol product.

Overall, the reaction involves the addition of a water molecule across the carbonyl group, resulting in the formation of an alcohol.
