The acidic character of alcohol is due to the

Options

A. non-polar nature of O-H bond
B. polar nature of O-H bond
C. non-polar nature of C-O bond
D. polar nature of C-O bond

Answer

### Step-by-Step Solution:

1. **Understanding Acidity**:
- Acidity in a substance is defined by its ability to donate protons (H⁺ ions). The more readily a substance can lose a proton, the stronger its acidic character.

2. **Identifying Alcohol Structure**:
- Alcohols are organic compounds characterized by the presence of one or more hydroxyl (–OH) groups attached to a carbon atom. The general formula for alcohols can be represented as R-OH, where R is an alkyl or aryl group.

3. **Analyzing the Hydroxyl Group**:
- In the hydroxyl group (–OH), the oxygen atom is more electronegative than the hydrogen atom. This difference in electronegativity creates a polar bond between oxygen and hydrogen.

4. **Polarity of the O-H Bond**:
- The O-H bond is highly polar due to the electronegativity of oxygen. This polarity means that the bond has a partial negative charge on the oxygen and a partial positive charge on the hydrogen.

5. **Proton Donation**:
- Because of the polarity of the O-H bond, the hydrogen atom can be easily released as a proton (H⁺ ion). This tendency to lose H⁺ ions is what contributes to the acidic character of alcohols.

6. **Conclusion**:
- Therefore, the acidic character of alcohol is primarily due to the polar nature of the O-H bond, which facilitates the release of H⁺ ions.

### Final Answer:
The acidic character of alcohol is due to the polar nature of the O-H bond, which allows for the easy release of H⁺ ions.
