Among the following the polar compound is .

Options

A. kerosene
B. alcohol
C. benzene
D. gasoline

Explanation

To determine which of the given compounds (Kerosene, Alcohol, Benzene, and Gasoline) is a polar compound, we need to analyze the structures and properties of each compound in relation to their dipole moments.

### Step-by-Step Solution:

1. **Understanding Polar Compounds**:
- Polar compounds are characterized by the presence of a dipole moment, which arises from the presence of polar bonds (bonds between atoms with different electronegativities) and an asymmetrical molecular shape.
- A dipole moment occurs when there is a separation of charge within the molecule, leading to a positive and a negative end.

2. **Analyzing Kerosene**:
- Kerosene is a hydrocarbon with a structure that consists mainly of carbon and hydrogen atoms. It has a non-polar character due to its symmetrical structure and lack of significant electronegative atoms.
- **Conclusion**: Kerosene is non-polar.

3. **Analyzing Alcohol**:
- Alcohols contain a hydroxyl (-OH) group, which consists of oxygen and hydrogen. Oxygen is highly electronegative, creating a significant dipole moment due to the difference in electronegativity between oxygen and hydrogen.
- The presence of the -OH group introduces polarity to the molecule, making it polar.
- **Conclusion**: Alcohol is polar.

4. **Analyzing Benzene**:
- Benzene is a cyclic hydrocarbon with a symmetrical structure. It has delocalized electrons due to resonance, which leads to a non-polar character.
- **Conclusion**: Benzene is non-polar.

5. **Analyzing Gasoline**:
- Gasoline is also a mixture of hydrocarbons and has a structure similar to kerosene, consisting mainly of carbon and hydrogen. It lacks polar functional groups and is generally considered non-polar.
- **Conclusion**: Gasoline is non-polar.

6. **Final Conclusion**:
- Among Kerosene, Alcohol, Benzene, and Gasoline, the only compound that exhibits polarity due to the presence of a polar -OH group is Alcohol.
- Therefore, the polar compound is **Alcohol**.

### Answer:
The polar compound among the given options is **Alcohol**.
