Naphthalene is an aromatic hydrocarbon comprising two fused benzene rings. It occurs in the essential oils of numerous plant species e.g. magnolia. Naphthalene appears as a white crystalline volatile solid with a strong coal-tar odor. The solid is denser than water and insoluble in water. Burns, but may be difficult to ignite.
