Acetylenedicarboxylic acid - Wikipedia

Acetylenedicarboxylic acid or butynedioic acid is an organic compound (a dicarboxylic acid) with the formula C 4 H 2 O 4 or HO 2 CC≡CCO 2 H.It is a crystalline solid that is soluble in diethyl ether.. The removal of two protons yields the acetylenedicarboxylate dianion C 4 O 2− 4, which consists only of carbon and oxygen, making it an oxocarbon anion.Partial ionization yields the ...
