    Coal tar is a thick, black liquid having an unpleasant smell which is obtained by heating coal in the absence of air. It is a mixture of 200 carbon compounds which includes benzene, toluene, phenol, aniline, anthracene and naphthalene.

    Uses:

    1. Coal tar is used to make synthetic fibres, drugs, plastics, synthetic dyes, paints, pesticides, etc.
    2. It has been traditionally used for metalling the roads. These days, bitumen, a petroleum product, is used in place of coal-tar for metalling the roads.
    3. Naphthalene balls used to repel moths and other insects are also obtained from coal tar.
