Is fluoranthene polar or nonpolar?
Fluoranthene is a polycyclic aromatic hydrocarbon (PAH). The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. Although samples are often pale yellow, the compound is colorless. It is soluble in nonpolar organic solvents.
Do PAHs dissolve in water?
Most PAHs do not dissolve in water but, instead, bind to sediments. When sediments become suspended in water, PAHs can be transported with the sediment. PAHs can enter groundwater from ash, tar, or creosote that is improperly disposed in landfills.
Is fluorene soluble in water?
Abstract. Fluorene or 9H-fluorene is a polycyclic aromatic hydrocarbon insoluble in water and soluble in many organic solvents.
What is fluoranthene used for?
Fluoranthene is released naturally during the burning of fossil fuels and wood. Fluoranthene is an ingredient in dyes, pharmaceuticals, and insulating oils.
How many rings does fluoranthene have?
The effects of structure and concentration of surfactants on the biodegradation of fluoranthene, a three rings polycyclic aromatic hydrocarbon in the aqueous phase, as well as their effects on the biodegradation and enzyme activity were investigated.
How does PAH get in water?
PAHs can reach water bodies mainly through dry and wet deposition, road runoff, industrial wastewater, leaching from creosote-impregnated wood, petroleum spills, and fossil fuel combustion [16-19]. They are generally teratogenic, carcinogenic, and mutagenic and may induce lung, bladder, as well as skin cancer.
What is PAH in water treatment?
Polynuclear aromatic hydrocarbons (PAHs) are a diverse group of chemical compounds with a similar arrangement of carbon and hydrogen atoms, formed as a result of incomplete combustion. Due to low water solubility and the ability to readily adsorb to particulate, PAHs are rarely a water treatment concern.
Is fluorene hydrophobic?
It is not controversial that fluorocarbon groups are hydrophobic. 6 However, whether the CF bond can participate in strong polar interactions is a matter of some debate. The CF bond is highly dipolar, as is evidenced by the large dipole moments (μ) of fluorinated hydrocarbons (Table 1).
Is fluorene solubility in diethyl ether?
Diethyl ether is the best solvent for dissolving the mixture, because though it is a polar molecule, its ethyl groups make it a nonpolar solvent. The compounds, fluorene and 1, 4-dibromobenzene, are also nonpolar; therefore, it would be easier for it to be dissolved in this organic solvent.

Is fluoranthene soluble in solvents?
Fluoranthene is a polycyclic aromatic hydrocarbon (PAH). The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. Although samples are often pale yellow, the compound is colorless. It is soluble in nonpolar organic solvents.
Is benzo b fluoranthene soluble in water?
IDENTIFICATION: Benzo(b)fluoranthene is a colorless needle. It is very insoluble in water. It is a member of a group of chemicals called polyaromatic hydrocarbons (PAHs). Benzo(b)fluoranthene is a substance that occurs as a result of incomplete burning.
What is the source of fluoranthene?
Fluoranthene is a constituent of coal tar and petroleum-derived asphalt. Currently, there is no known production or use of this compound. Since it is a universal product of combustion of organic matter and is present in fossil fuel products, fluoranthene is generally released into air and water.
Is fluoranthene metabolized in plant cell cultures?
The metabolism of fluoranthene was investigated in 11 cell cultures of different plant species using a [14C]-labeled standard. Most species metabolized less than 5% of fluoranthene to soluble metabolites and formed less than 5% nonextractable residues during the standardized 48-hr test procedure.
