==History and etymology==
The radical was first reported by [[Henri Victor Regnault]] in 1835 and initially named ''aldehydène''. Due to the incorrect measurement of the [[atomic mass]] of carbon it was believed to be {{chem2|C4H6}} at the time. Then in 1839 it was renamed by [[Justus von Liebig]] to "[[acetyl]]", because he believed it to be the radical of the [[acetic acid]].<ref>{{Cite journal |last1=Constable |first1=Edwin C. |last2=Housecroft |first2=Catherine E. |date=2020-04-20 |title=Before Radicals Were Free – the Radical Particulier of de Morveau |journal=Chemistry |language=en |volume=2 |issue=2 |pages=293–304 |doi=10.3390/chemistry2020019 |issn=2624-8549|doi-access=free }}</ref>

The modern term was coined by German chemist [[Hermann Kolbe]] in 1851, who rebutted Liebig's hypothesis.<ref>H. Kolbe (1851), [https://books.google.com/books?id=jJ8wAAAAYAAJ&pg=PA369 "On the chemical constitution and nature of organic radicals,"] ''The Quarterly Journal of the Chemical Society of London'', '''3''' (4) :  369-405; see footnote on [https://books.google.com/books?id=jJ8wAAAAYAAJ&pg=PA376 page 376.]</ref> However even in 1860 [[Marcellin Berthelot]] still based the name he coined for [[acetylene]] on Liebig's nomenclature and not on Kolbe's.

The [[etymology]] of "vinyl" is the [[Latin]] ''vinum'' = "[[wine]]", and the [[Greek language |Greek]] word "hylos" 'υλος (matter or material), because of its relationship with [[Ethanol|ethyl alcohol]].
