Wikizero - Acide acétique

L'acide éthanoïque ou acide acétique est un acide carboxylique avec une chaîne carbonée théorique en C2, analogue à l'éthane, de masse molaire 60 g/mol et de formule chimique brute C 2 H 4 O 2, semi-développée CH 3-CO-OH ou formation courte AcOH, où Ac signifie « CH 3 CO » [22], du groupe acétyle.L'adjectif du nom courant provient du latin acetum, signifiant vinaigre.
