Diethyl ether to ethanol

Explanation

To convert diethyl ether (C2H5)2O to ethanol (C2H5OH), we can follow these steps:

### Step 1: Protonation of Diethyl Ether
- **Reaction**: Add concentrated sulfuric acid (H2SO4) to diethyl ether.
- **Explanation**: The sulfuric acid protonates the ether oxygen, making it a better leaving group.

### Step 2: Nucleophilic Attack by Water
- **Reaction**: Introduce water (H2O) to the reaction mixture.
