hydrocarbon

 [hi″dro-kahr´bon]
an organic compound that contains carbon and hydrogen only.
alicyclic hydrocarbon one that has cyclic structure and aliphatic properties.
aliphatic hydrocarbon one in which no carbon atoms are joined to form a ring.
aromatic hydrocarbon one that has cyclic structure and a closed conjugated system of double bonds.
chlorinated hydrocarbon any hydrocarbon compound with chlorine substitutions; many are toxic. They are used mainly as refrigerants, industrial solvents, dry cleaning fluids, and insecticides (such as ddt and dieldrin). Some have been used as anesthetics, such as chloroform.
