/ˈɛθeɪn/, U.S.

/ˈɛˌθeɪn/

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: eth- comb. form, -ane suffix².

Etymology: < eth- comb. form + -ane suffix², after German Aethan (A. W. Hofmann 1866, in Monatsbericht der Königl. Preuss. Akad. der Wissenschaften zu Berlin, 1865 653; also Äthan and (now usually) Ethan).

Chemistry.

A flammable gaseous hydrocarbon that is the second member of the alkane series and occurs in petroleum and natural gas. Formerly also called dimethyl.Formula: C₂H₆.
