WitrynaPhysical Properties The chemical formula for naphthalene is C10H8, and its molecular weight is 128.19 g/mol. (1) Naphthalene occurs as a white solid or powderthat is … WitrynaThe substance crystallizes in lustrous white plates, melting at 80.1° C (176.2° F) and boiling at 218° C (424° F). It is almost insoluble in water. Naphthalene is highly volatile and has a characteristic odour; it has been used as moth repellent. A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). The eight carbon atoms that are not shared by the two rings carry … Zobacz więcej Naphthalene is an organic compound with formula C 10H 8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 Zobacz więcej Reactions with electrophiles In electrophilic aromatic substitution reactions, naphthalene reacts more readily than benzene. For example, chlorination and … Zobacz więcej Naphthalene is used mainly as a precursor to derivative chemicals.
