The chemistry of the nitrite ion and HNO2: (a) Two resonance structures are possible for NO2−. Draw these structures, and then find the formal charge on each atom in each resonance structure. (b) In forming the acid HNO2 an H+ ion attaches to the O atom and not the N atom of NO2−. Explain why you would predict this result. (c) Two resonance structures are possible for HNO2. Draw these structures, and then find the formal charge on each atom in each resonance structure. Is either of these structures strongly preferred over the other?

(a)

Interpretation Introduction

Interpretation:

Number of Resonance structures do each species have, has to be determined.

Concept Introduction:

Formal charge: It is the electrostatic charge that would reside on an atom in a molecule or polyatomic ion if all bonding electron are shared equally between pairs of atoms.

Formal charge calculation: The formal charge for atom in a molecule or ion is calculated based on the Lewis structure of the molecule or ion by following the given equation below:

Formal charge calculation of molecule or ion =NVE-{LPE+12(BE)

Resonance structures:

A molecule or ion which show more than structure but none of them are accurately correct show the known property of that molecule, and can lie between the canonical structure is known as resonance or canonical or contributing structure.

Explanation

Here NO2, two resonance structures are possible. These structures are drawn below.

Formal charge: It is the electrostatic charge that would reside on an atom in a molecule or polyatomic ion if all bonding electron are shared equally between pairs of atoms

(b)

Interpretation Introduction

Interpretation:

A proton attached to an O-atom or to the N-atom of nitrate ion has to be predicted.

Interpretation Introduction

Interpretation:

A proton attached to an O-atom or to the C-atom of carbonate ion has to be predicted.
