Can naphthalene balls dissolve in water?
Naphthalene evaporates easily. That is why you can smell mothballs. Some naphthalene will dissolve in water in rivers, lakes, or wells. Naphthalene in water is destroyed by bacteria or evaporates into the air.
Why naphthalene dissolves in benzene not in water?
Since naphthalene is a covalent nonpolar substance, it is soluble in a nonpolar solvent like benzene but insoluble in polar solvent like water.
Can you dissolve naphthalene?
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.
What happens when water is added to naphthalene?
The heat of solution of naphthalene in water is positive and becomes more positive as the TMU concentration is increased. This heat term is more than overcome by a concomitant large increase in the entropy of solution, the net effect being to solubilize the hydrocarbon by the addition of tetramethylurea.
Why naphthalene dissolves in benzene but not in water Shaalaa?
Explanation: Naphthalene is insoluble in water because it is non-polar. This means that it cannot participate in dipole-dipole interactions or hydrogen bonding.
How does naphthalene get into 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 is non polar?
Naphthalene is a non-polar molecule. This is because a bond between carbon and hydrogen has an electronegativity value of 0.4 and naphthalene consists…
Why naphthalene is soluble in chloroform?
These hydrocarbons are therefore powerful solvents for a wide range of polar and nonpolar compounds. Naphthalene, which is nonpolar, and phenol (C 6H 5OH), which is polar, are very soluble in chloroform.
How does naphthalene get in water?
Does naphthalene dissolve 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 naphthalene is soluble in ether or benzene?
The answer would be Naphthalene Dissolves in ether or benzene due to Similar London Dispersion forces. London Dispersion force is the weakest intermolecular force.It is also called London Force. These forces acts between Atoms and molecules. This force is sometimes also called induce dipole-dipole interaction.
