Encyclopedic overview
Fulminic acid is an acid with the formula HCNO, more specifically H−C≡N−O. It is an isomer of isocyanic acid (H−N=C=O) and of its elusive tautomer, cyanic acid (H−O−C≡N), and also of isofulminic acid (H−O−N≡C).
Fulminate is the anion [C≡N−O] of any of its salts. For historical reasons, the fulminate functional group is understood to be −O−N≡C as in isofulminic acid; whereas the group −C≡NO is called nitrile oxide.
