What is the solubility of naphthalene in water and ethanol?
It melts at 80°C, boils at 218°C, and sublimes upon heating. It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and very soluble in ether, chloroform, or carbon disulfide. Naphthalene is obtained from coal tar, a byproduct of the coking of coal.
Is naphthalene more soluble in ethanol?
Answer and Explanation: Naphthalene is highly nonpolar and therefore will not dissolve in water, ethanol, or other polar solvents.
Why is naphthalene soluble in ethanol?
Explanation. Naphthalene is a nonpolar compound. Thus, it is insoluble in highly polar solvents like water. Non-polar solutes do not dissolve in polar solvents like water because they cannot compete with the strong attraction that the polar solvent molecules have for each other.
Is ethanol miscible in naphthalene?
As an aromatic hydrocarbon, naphthalene’s structure consists of a fused pair of benzene rings….Naphthalene.

Does naphthalene dissolve in water?
At hazardous waste sites and landfills, naphthalene can dissolve in water, attach to soil, and leach into underground drinking water. Some naphthalene dissolves in rivers, lakes, or wells and evaporates within two weeks. Bacteria destroy naphthalene in water.
What happens when naphthalene mixed with water?
Naphthalene is insoluble in water because it is non-polar. This means that it cannot participate in dipole-dipole interactions or hydrogen bonding…
Is naphthalene more soluble in ethanol or benzene?
It that is never clean is more soluble in benzene because both of these substances are non polar, so they can be dissolve while if I’m talking about in case of ethanol which is C two H five, this is a polar molecule.
What happens when naphthalene is added to water?
Napthalene balls do not dissolve in water. So no chance for changing and the property of napthalene should not change.
Is ethanol soluble in water?
Ethanol is actually miscible in water, which means that the two liquids can be mixed in any proportion without any limit to their solubility.
How does naphthalene get in water?
Naphthalene enters the environment when factories produce it, when accidental spills occur, when moth repellents vaporize, or when wood or tobacco burn. At hazardous waste sites and landfills, naphthalene can dissolve in water, attach to soil, and leach into underground drinking water.
Why naphthalene dissolves in benzene but not in water?
Explanation: Naphthalene is insoluble in water because it is non-polar. This means that it cannot participate in dipole-dipole interactions or hydrogen bonding.
Why naphthalene dissolves in benzene and not in water?
1 Answer. Since naphthalene is a covalent nonpolar substance, it is soluble in a nonpolar solvent like benzene but insoluble in polar solvent like water.
