Question
The carbonyl carbon is electrophilic and can undergo
nucleophilic attack by carbon, oxygen, sulfur and
nitrogen-containing nucleophiles. In this tutorial, we will
focus on oxygen-containing nucleophiles, which form
hydrates, hemiacetals and acetals. This tutorial will cover
1. formation of geminal diols or hydrates and when this
reaction is favorable
2. formation of hemiacetals
3. formation of acetals
4. hydrolysis of hemiacetals and acetals
5. acetals as protecting groups

Step 4: The acetal formation mechanism is also reversible.
The reaction can be driven in the forward reaction by using
an excess of alcohol and driven in the reverse direction by
using an excess of water.
Analyze the reaction shown:
excess H₂O*
?
