Apr 15, 2016 · The bond order for NO− 2 is 3 electrons 2 bonding groups = 3/2 = 1.5. The bond order for NO− 3 is 4 electrons 3 bonding groups = 4/3 ≈ 1.33. So, you can see the bond order decreases as the number of oxygens in these NOk± n compounds increases. The higher the bond order, the stronger the bond and thus the shorter the bond. Now that you know the number of valence electrons per element, you need to compute the total valence electrons for the NO_3^"-1" ion. 5 + (3 x 6) = 23 electrons But since the whole molecule has a -1 charge, you need to add this too. So the total number of valence electrons is 24. The next thing to do is draw.Resonance theory is explained below using the nitrate ion as the example. According to resonance theory, the structure of the nitrate ion is not 1 nor 2 nor 3 but the average of all three of them, weighted by stability.

Think about placing the two structures on top of each other, this is what our hybrid should look like: Since the resonance hybrid is a combination of the two resonance structures we see that we have a -1/2 formal charge on each of the oxygens and the bonds between the N and Os is 1 and 1/2 or 1.5 (or 3/2).

Delocalization, Conjugated Systems, and Resonance Energy. The presence of alternating π π and σ σ bonds in a molecule such as benzene is known as a conjugated system, or conjugated π π bonds. Conjugated systems can extend across the entire molecule, as in benzene, or they can comprise only part of a molecule.

Ortho and para attack produces a resonance structure which places the arenium cation next to an additional cation. This destabilizes the arenium cation and slows down ortho and para reaction. By default the meta product forms faster because it lacks ...In this structure, the central atom has a zero charge; Sulphur has a charge of +2, and Nitrogen has a charge of -1. In total, the ion has a charge of -1. The first two resonance structures are more frequently used as it is more relevant. However, the first structure is more stable and often used as the Lewis structure representation for SCN ion.The empirical resonance energy can be determined by comparing the enthalpy change of hydrogenation of the actual substance to that of the contributing structure.
