How is naphthalene classified?
How is naphthalene classified?
Naphthalene is classified as Group C, possible human carcinogen, by the U.S. EPA. This is based on limited evidence of carcinogenicity following inhalation exposure in animals, and lack of data for humans.
Is naphthalene balls 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 acid soluble in water?
Naphthalene is a nonpolar compound. Thus, it is insoluble in highly polar solvents like water.
What are the properties of naphthalene?
Properties of Naphthalene:
- Naphthalene exists in crystalline form.
- Naphthalene is generally white in colour.
- The molecular weight of naphthalene is 128.18 g/mol.
- Naphthalene is insoluble in water at a normal room temperature.
- Naphthalene has an aromatic odour.
- The vapour pressure of naphthalene is 0.087 mmHg.
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].
What is naphthalene soluble?
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 a polar solvent?
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.
Is Naphthalene a polar solvent?
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.
In which solvent is naphthalene soluble insoluble?
What does solvent dissolve naphthalene?
Naphthalene is a nonpolar compound. Thus, it is insoluble in highly polar solvents like water. Beside this, what can 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.
What is the boiling point of naphthalene?
The melting point of naphthalene is approximately between 79 and 82 degrees Celsius. The physical state of this chemical is as a white solid that is insoluble in water. This chemical also has a boiling point between 217 and 218 degrees Celsius.
What is the molar mass of naphthalene?
Answer and Explanation: The molar mass of naphthalene is 128.17052 g/mol. Naphthalene’s chemical formula C10 H8 tells us that there are 10 carbon atoms and 8 hydrogen atoms. Carbon’s molar mass is 12.0107 g/mol. Ten carbon atoms means we multiply carbon’s molar mass by ten.
What are the uses of naphthalene?
Naphthalene is an aromatic hydrocarbon found in coal tar or crude oil. Naphthalene is used in the manufacture of plastics, resins, fuels, and dyes. It is also used as a fumigant insecticide that works by turning directly from a solid into a toxic vapor. This process is called sublimation.
