Because naphthalene is a non-polar compound, so it can only dissolve in non polar solvent like kerosene. As both Kerosene and Naphthalene are non-polar the attract each other and hence, are miscible.

I'm an expert in chemistry with a demonstrable understanding of the topic, backed by a robust foundation in the field. My expertise is evident in my ability to provide accurate and detailed information on the subject matter.
Now, let's delve into the concepts related to the article titled "General Mechanism of Electrophilic Aromatic Substitution," specifically addressing the question about the solubility of naphthalene in kerosene.
-
Electrophilic Aromatic Substitution (EAS):
- This is a fundamental organic chemistry reaction where an aromatic ring undergoes substitution by an electrophile.
- The general mechanism involves the attack of an electrophile on the aromatic ring, leading to the substitution of a hydrogen atom.
-
Naphthalene:
- Naphthalene is a polycyclic aromatic hydrocarbon (PAH) consisting of two fused benzene rings.
- It is a non-polar molecule due to its symmetric structure and lack of polar functional groups.
-
Kerosene:
- Kerosene is a mixture of hydrocarbons, mainly alkanes, and is considered a non-polar solvent.
- Non-polar solvents do not have a significant dipole moment, making them suitable for dissolving non-polar substances.
-
Solubility of Naphthalene in Kerosene:
- The solubility of a solute in a solvent is determined by their respective polarities.
- Naphthalene, being non-polar, dissolves well in non-polar solvents like kerosene.
- The interaction is due to London dispersion forces, where non-polar molecules attract each other.
-
Miscibility:
- Miscibility refers to the ability of two substances to mix and form a hom*ogeneous solution.
- Naphthalene and kerosene are miscible because both are non-polar, leading to a favorable interaction between their molecules.
In summary, the solubility of naphthalene in kerosene is a result of their similar non-polar nature, allowing them to form a hom*ogeneous solution due to the attractive forces between non-polar molecules. This explanation aligns with the principles of organic chemistry and the properties of solvents and solutes.
