Naphthalene is one of the simplest dense cyclic hydrocarbons consisting of two benzene rings. Naphthalene with the chemical formula C10H8 is an important raw material that is used in the manufacture of dyes and synthetic resins.
Naphthalene is mainly obtained from coal and crude oil and is used in the production of various chemicals.
Naphthalene participates in general and general reactions of aromatic compounds. These reactions are of the type of electrophilic substitution, during which an electron-deficient (electrophile) species replaces one of the hydrogens in the naphthalene molecule and produces two types of isomeric products.
Another reaction in which naphthalene participates is the combustion reaction, which is common to almost all organic substances. Like most aromatic substances, naphthalene produces soot in addition to water and carbon dioxide when burned (incomplete combustion).
