No2 resonance.

Solution. NO2, the nitro group is an EWG (electron-withdrawing group) and hence meta-directing. When you draw the resonance structures, you can see that the ortho and para positions are those that can hold the electron density or positive charge that a substituent group provides. Since NO2 is an EWG, it will pull the electron density away from ...

The carbocation intermediate in electrophilic aromatic substitution (the benzenonium ion) is stabilized by charge delocalization (resonance) so it is not subject to rearrangement. In principle it could react by either mode 1 or 2, but the energetic advantage of reforming an aromatic ring leads to exclusive reaction by mode 2 ( ie. proton loss).For NO2- and SO2 1) Draw a Lewis dot structure. 2) Determine whether additional resonance structures are needed to adequately depict this molecule.

It is a weak acid and exists only in specific conditions, i.e., in solution (cold and dilute), as a gas, or in the form of nitrite salts. It appears to be pale blue as a solution. Its existence in these peculiar states is due to the fact that HNO2 is unstable and decomposes rapidly in its free form.Bond order is the number of chemical bonds between a pair of atoms and indicates the stability of a bond. For example, in diatomic nitrogen, N≡N, the bond order is 3; in acetylene, H−C≡C−H, the carbon-carbon bond order is also 3, and the C−H bond order is 1.
