Which of the following is basic ?

Options

A. `CH_3 CH_2 OH`
B. `H-O-O-H`
C. `HO-CH_2-CH_2-OH`
D. `H_(3)C-underset(O)underset(||)(C)-OH`

Explanation

To determine which of the given compounds is basic, we will analyze each compound one by one based on their functional groups and the effects they exhibit.

### Step-by-Step Solution:

1. **Identify the Compounds**: The given compounds are:
- Ethanol (C2H5OH)
- Hydrogen Peroxide (H2O2)
- Ethane-1,2-diol (C2H6O2)
- Acetic Acid (CH3COOH)

2. **Analyze Acetic Acid**:
- Acetic acid is a carboxylic acid. It has a carboxyl group (-COOH) that can donate a proton (H+), making it acidic.
- **Conclusion**: Acetic acid is acidic.

3. **Analyze Ethane-1,2-diol**:
- Ethane-1,2-diol contains two hydroxyl groups (-OH). While it can form hydrogen bonds and has some acidic properties, it is not strongly basic.
- The presence of the -OH groups can lead to some acidity, but it is not a base.
- **Conclusion**: Ethane-1,2-diol is not basic.

4. **Analyze Hydrogen Peroxide**:
- Hydrogen peroxide (H2O2) contains a peroxide bond (O-O) and has some acidic properties due to the presence of oxygen.
- It can act as a weak acid but does not exhibit basic properties.
- **Conclusion**: Hydrogen peroxide is not basic.

5. **Analyze Ethanol**:
- Ethanol (C2H5OH) has a hydroxyl group (-OH) and can act as a weak base. The ethyl group (C2H5) is an electron-donating group (due to +I effect), which can enhance the basicity of the hydroxyl group.
- Ethanol can accept protons, making it a weak base.
- **Conclusion**: Ethanol is basic.

6. **Final Conclusion**:
- Among the four compounds, only ethanol is basic.

### Answer:
The only basic compound among the given options is **Ethanol (C2H5OH)**.
