The nitrate anion is the conjugate base of nitric acid, ... Like the isoelectronic carbonate ion, the nitrate ion can be represented by three resonance structures:
Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −. It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1] The dominant application of azides is as a propellant in ...
Formal charges in ozone and the nitrate anion. In chemistry, a formal charge (F.C. or q*), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.
Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure ...
3 anion, are well-known, as are Sr(N 3) 2 and Ba(N 3) 2. Azides of the B-subgroup metals (those in groups 11 through 16) are much less ionic, have more complicated structures, and detonate readily when shocked. [4] Mesomeric structures of borazine, (–BH–NH–) 3. Many covalent binary nitrides are known.
Approximately 66% of the time, these two radicals recombine to form carbon dioxide and nitrate. The other 33% of the time, these two radicals escape the solvent cage and become free radicals. It is these radicals ( carbonate radical and nitrogen dioxide ) that are believed to cause peroxynitrite-related cellular damage.
The two canonical structures of NO − 2, which contribute to the resonance hybrid for the nitrite ion Dimensions of trans-HONO (from the microwave spectrum) The nitrite ion has a symmetrical structure (C 2v symmetry), with both N–O bonds having equal length and a bond angle of
