a hydrocarbon that contains two carbon-to-carbon double bonds in its molecules
Word origin
from di-1 + -ene
-diene in British English
combining form in countable noun
denoting an organic compound containing two double bonds between carbon atoms
butadiene
Word origin
from di-1 + -ene
diene in American English
(ˈdaiin, daiˈin)
noun
Chemistry
any compound, as 1,3-butadiene, CH2=CH−CH=CH2, that contains two double bonds
Also called: diolefin
Word origin
[1915–20; di-1 + -ene]This word is first recorded in the period 1915–20. Other words that entered Englishat around the same time include: GI, camouflage, feedback, soviet, takeoutdi- is a prefix occurring in loanwords from Greek, where it meant “two,” “twice,” “double”(diphthong). On this model, di- is freely used in the formation of compound words (dicotyledon; dipolar) and in chemical terms (diatomic; disulfide); -ene is a suffix used to form names of unsaturated hydrocarbons (anthracene; benzene), esp. those of the alkene series (butylene)
