Why naphthalene is soluble in water?

Why naphthalene is soluble in water?

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 naphthalene soluble in water Yes or no?

Naphthalene is insoluble in water because it is non-polar. This means that it cannot participate in dipole-dipole interactions or hydrogen bonding…

What is the chemical properties of naphthalene?

Naphthalene has a molecular weight of 128.18 g/mol. At room temperature, naphthalene is insoluble in water. The odour of naphthalene is aromatic. Naphthalene has a vapour pressure of 0.087 mmHg.

Where is naphthalene soluble?

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 soluble in oil?

naphthalene năf´thəlēn˝ [key], colorless, crystalline, solid aromatic hydrocarbon with a pungent odor. 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.

Is naphthalene soluble in organic solvent?

an aromatic hydrocarbon; colorless lamellar crystals with a characteristic odor. Melting point, 80.3°C; boiling point, 218°C; density, 1.1517 g/cm3 (15°C). Naphthalene is volatile; it sublimes at 50°C. It is poorly soluble in water but dissolves readily in most organic solvents; it is distilled over steam.

Is naphthalene soluble in methanol?

Treatment with methanol alone gives low extraction efficiency although its recovery by crystallization and precipitation of naphthalene is very easy. This is due to a solubility of 5.3% methanol in the fuel and a rapid saturation of 6% of naphthalene in methanol [3].

Why is naphthalene insoluble in water?

Naphthalene cannot dissolve in water since Naphthalene is a sublimable solid (i.e. , it can change from solid phase to gas phase. It doesn’t have a liquid phase). Hence, Naphthalene cannot be dissolved. Although solids can be dissolved in liquids but when naphthalene breaks down it turns into gas.

What does solvent dissolve naphthalene?

Naphthalene does not dissolve in water, but dissolves well in most organic (carbon-containing) solvents. The most common use of Naphthalene is in moth repellants, such as mothballs. It is also used to make dyes, leather tanning agents, resins, lubricants, antiseptics, toilet deodorants and other insecticides.

Does naphthalene dissovled 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. Naphthalene does not build up in the flesh of animals and fish.

Does naphthalene dissolve in hot water?

Naphthalene appears as a white crystalline volatile solid with a strong coal-tar odor. The solid is denser than water and insoluble in water. Burns, but may be difficult to ignite. . In the molten form it is very hot. Exposure to skin must be avoided.
