Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) composed of three fused benzene rings, resulting in a bicyclic structure. It is a colorless crystalline solid at room temperature naturally found in coal tar, crude oil, and various fossil fuels. Phenanthrene is a prominent PAH family member and is a fundamental building block in organic chemistry and […]
Anthracene is a polycyclic aromatic hydrocarbon consisting of three fused benzene rings. It is a solid at room temperature, typically appearing as colorless to pale yellow crystals. Anthracene is insoluble in water but soluble in organic solvents such as benzene and toluene. Anthracene exhibits several physical properties: These properties contribute to its diverse applications in […]
Naphthalene is a white, crystalline solid with a distinct odor reminiscent of mothballs. It slowly sublimes at room temperature, generating a highly flammable vapor.  John Kidd (1775–1851), an English chemist and physician, is credited with discovering naphthalene from coal tar in 1819. It contains a complex hydrocarbon mixture similar to what is found in petroleum. […]
