anybody of three metameric hydrocarbons C4H8 of this ethylene show they truly are gaseous or easily liquefiable labeled as also butene
- some of three isomeric hydrocarbons C4H8; all found in making synthetic rubbers
- anybody of three metameric hydrocarbons, C4H8, of the ethylene series. These are typically gaseous or easily liquefiable.
(letter.) Anybody of three metameric hydrocarbons, C4H8, regarding the ethylene series. They are gaseous or easily liquefiable.
IroXb, many) was chosen for compounds like butylene, C 4 H 8, and ethylene, C 2 H 4, corresponding to the same composition in weight but differing in molecular formula, and having different densities in gas or vapour, a litre of butylene and isobutylene weighing, for instance, under ordinary temperature and pressure, about 2.5 gr., ethylene only one-half as much, since density is proportional to molecular weight.
