Question

What solvent dissolves naphthalene?

Answer 1

A solvent is a liquid that dissolves a solute and forms a solution as a result. A liquid is the most common kind of solvent, but it may also be a solid, a gas, or a supercritical fluid. Water is the most common solvent used for living organisms and a solvent for polar molecules; all ions and proteins in a cell are dissolved in water within the cell.

Complete answer:
The organic compound naphthalene has the formula ${C_{10}}{H_8}$. It's the simplest polycyclic aromatic hydrocarbon, and it's a white crystalline solid with a distinct odour observable at concentrations as low as 0.08 parts per million by density. The composition of naphthalene as an aromatic hydrocarbon is made up of a fused pair of benzene rings. It's well known for being the principal ingredient in mothballs.
Naphthalene is a polar nonpolar substance. As a result, it's insoluble in polar solvents like water. Since non-polar solutes cannot deal with the intense affinity that polar solvent molecules have with each other, they do not dissolve in polar solvents like water. Nonpolar and partially polar solvents such as benzene, toluene, and carbon disulphide, on the other hand, are soluble in it.
Liquids or solvents with no dipole moment are known as non-polar solvents. As a consequence, there are no partial positive or negative charges in the solvents. In essence, their electronegativity differs just slightly. We may also assume that atom-to-atom bonds have identical electronegativity. Since there are no opposite charges and the polar compound is not drawn, non-polar solvents cannot dissolve polar compounds. These molecules are often referred to as "non-polar" due to their lack of partial charge.

Note:
Naphthalene is a sturdy polycyclic hydrocarbon that is white in colour and has a heavy mothball odour.
Coal tar or petroleum distillation are also used to make naphthalene.
Plastics, resins, oils, and dyes all use naphthalene as a raw material.
