The nitronium ion, [ N O 2]+, is a cation. It is an onium ion because its nitrogen atom has +1 charge, similar to ammonium ion [NH4]+. It is created by the removal of an electron from the paramagnetic nitrogen dioxide molecule NO2, or the protonation of nitric acid HNO3 (with removal of H2O ). [2] May be toxic by ingestion. Used to make other chemicals. Nitrite is the nitrogen oxoanion formed by loss of a proton from nitrous acid. It has a role as a human metabolite.

This is important because neither resonance structure actually exists, instead there is a hybrid. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom. 2 comments.The $\ce{N-O}$ bonds in the $\ce{NO2-}$ ion are equal in length, whereas they are unequal in $\ce{HNO2}$. Explain.

There are a number of compounds and polyatomic ions that cannot be written using one single structure. This was known even back to the early beginnings of structural chemistry in the mid-1850s. These substances must be described in terms of "intermediate" structures, possessing non-integral bonds such as one and one-half bonds or one ...When a molecule has nonequivalent resonance structures, one structure may contribute more to the resonance hybrid than another. In terms of formal charge, a structure generally contributes more when (1) the formal charges on the atoms are minimized and (2) any negative formal charges are on more electronegative atoms and any positive charges are on more electropositive atoms.Formal charge on atom in a molecule= (total no. of valence electrons in the free atom)- (total no. of non-bonding electrons)-1/2 (total no. of bonding electrons)Formal charge on double bonded O atom =6–4–0.5(4)=0Formal charge on single bonded O atom =6–6–0.5(2)=−1.Draw Lewis structures of all the important resonance forms of NO2-arrow_forward.

Which type of electron delocalization affects the acidity of the two amine groups, resonance or the inductive effect?2.16. 0.23. 0. As can be seen from the data, as the electronegativity of X increases the chemical shift, δ increases. This is an effect of the halide atom pulling the electron density away from the methyl group. This exposes the nuclei of both the C and H atoms, "deshielding" the nuclei and shifting the peak downfield.Since NO 2 is an electron withdrawing group, a glance at the resonance structures shows that the positive charge becomes concentrated at the ortho-para positions. Thus these positions are deactivated towards electrophilic aromatic substitution. Hence, NO 2 is a meta-director, as we all learned in organic chemistry.. Similarly, determine whether -CH 3 is ortho-para directing or meta-directing ...NO2 resonance structure.
