Which statements about this are correct? 10 The two resonance structures contribute equally to the structure. II. The formal charge of nitrogen is zero in both resonance structures, O Both I and II O ll only O Neither I nor II O I only.Lewis structures, also known as Lewis dot diagrams,Lewis dot formulas,Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. In nitrite ion, For Nitrogen we have 5 valence electrons; 6 ...For the nitrite ion (NO2-), there is one single bond and one double bond between the nitrogen and oxygen. This leads to a resonance structure that effectively makes the bond lengths 1.5 each. For the nitrate ion (NO3-), there is one double bond that leads to resonance amongst all three of the nitrogen-oxygen bonds.

Resonance effect is the conjugation between the ring and the substituent, which means the delocalizing of the \(\pi\) electrons between the ring and the substituent. ...

This page titled 8.4: Formal Charge is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by Robert Belford .NO 2 is, in fact, bent (the bond angle is 136°). The two most important resonance structures are shown below. The formal charges, combined with the bent geometry, means that the molecule as a whole is polar, since it has a positive end (nitrogen) and a negative end (the oxygen atoms). If NO 2 were linear, it would not be polar any …Examples are NO 2, carbonyl groups (C=O), sulfonyl, cyano (CN) among others. These groups are universally deactivating , slowing the rate of electrophilic aromatic substitution. In terms of resonance, one can draw a pi bond from the aromatic ring forming a pi bond with the atom bound to the ring, resulting in formation of a new lone pair on an ...May be toxic by ingestion.
