hydrocarbons, acyclic |
Organic compounds composed exclusively of carbon and hydrogen where no carbon atoms join to form a ring structure. (12 Dec 1998) |
hydrocarbons, alicyclic |
Organic compounds composed exclusively of carbon and hydrogen. Three or more carbon atoms are arranged in a cyclic structure and they possess aliphatic properties. (12 Dec 1998) |

Organic compounds composed exclusively of carbon and hydrogen. They are unsaturated hexagonal ring structures with a closed conjugated system of double bonds that gives them the characteristic chemical properties of the parent aromatic hydrocarbon, benzene. (12 Dec 1998) |
hydrocarbons, cyclic |
Organic compounds composed exclusively of carbon and hydrogen forming a closed ring that may be either alicyclic or aromatic. (12 Dec 1998) |
