Acetylene vs. Ethylene

Acetylenenoun

Any organic compound having one or more carbon–carbon triple bonds; an alkyne.

Acetylenenoun

Ethyne; the simplest alkyne, a hydrocarbon of formula HC≡CH. It is a colourless, odorless gas, formerly used as an illuminating gas, but now used in welding or metallurgy.

Acetylenenoun

A gaseous compound of carbon and hydrogen, in the proportion of two atoms of the former to two of the latter. It is a colorless gas, with a peculiar, unpleasant odor, and is produced for use as an illuminating gas in a number of ways, but chiefly by the action of water on calcium carbide. Its light is very brilliant.

Acetylenenoun

a colorless flammable gas used chiefly in welding and in organic synthesis

Acetylene

Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne.

Ethylenenoun

(organic compound) The common name for the organic chemical compound ethene. The simplest alkene, a colorless gaseous (at room temperature and pressure) hydrocarbon with the chemical formula C2H4.

Ethylenenoun

(organic chemistry) The divalent radical derived from ethane.

Ethylenenoun

A colorless, gaseous hydrocarbon, C2H4, forming an important ingredient of illuminating gas, and also obtained by the action of concentrated sulphuric acid in alcohol. It is an unsaturated compound and combines directly with chlorine and bromine to form oily liquids (Dutch liquid), - hence called olefiant gas. Called also ethene, elayl, and formerly, bicarbureted hydrogen.

Ethylenenoun

a flammable colorless gaseous alkene; obtained from petroleum and natural gas and used in manufacturing many other chemicals; sometimes used as an anesthetic

Ethylene

Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C2H4 or H2C=CH2. It is a colorless flammable gas with a faint odor when pure.
