The cyanate ion (OCN−) and the fulminate ion (CNO−) share the same three atoms, but have vastly different properties. The cyanate ion is stable, while the fulminate ion is unstable and forms explosive compounds. The resonance structures of the cyanate ion were explored in Example.Click to see full answer. Also to know is, does OCN have resonance?Assign formal charges to each atom in the resonance forms of the cyanate ion (OCN−). Lewis structure shows the bonding between the atoms present in a molecule or molecular ion and shows lone pair of electrons also. Both the cyanate ion ( ) and the fulminate ion ( ) have same atoms.Beside above, which resonance form a B or C is the preferred structure of the fulminate ion? Structure (b) is preferred because the negative charge is on the more electronegative atom (N), and it has lower formal charges on each atom as compared to structure (c): 0, −1 versus +1, −2. Salts containing the fulminate ion (CNO −) are used in explosive detonators. Likewise, does so2 have resonance? Sulfur dioxide, or SO2 , has two resonance structures which contribute equally to the overall hybrid structure of the molecule. However, a third Lewis structure can be drawn for SO2 which is more stable in theory, but doesn’t quite match experimental data.Which is the best Lewis structure for the fulminate ion CNO -)?B. C. Carbon has the negative charge (-3) while oxygen (which is more electronegative) has a (+1) formal charge. Therefore, the best Lewis structure for fulminate ion is structure B.
