-yne

From Wikipedia, the free encyclopedia

The suffix -yne is used in organic chemistry to form names of organic compounds containing the -C≡C- group, known generally as alkynes. Sometimes a number between hyphens is inserted before it to state which atoms the triple bond is between. This suffix arose as a collapsed form of the end of the word "acetylene". The final "-e" disappears if it is followed by another suffix that starts with a vowel.
