Question

Give the resonating structures of $N{{O}_{2}}$and ${{N}_{2}}{{O}_{5}}$

Answer 1

We know the meaning of resonating structure. From this we have to draw the all delocalization of lone pairs, negative and positive charge etc.

Complete step by step solution:

We know that resonance is the way by which we describe delocalized electrons within certain molecules or polyatomic ions where the bonding can’t be expressed by a single Lewis formula or structure.
Resonance structures: These are the set of two or more Lewis Structures that collectively describe the electronic bonding of a single polyatomic species including partial bonds and partial charges.
Resonance structures are capable of describing delocalized electrons that cannot be expressed by a single Lewis formula with an integer number of covalent bonds.
In case of$N{{O}_{2}}$,it has one single bonded oxygen and one double bonded oxygen. Or we can say that this double bond delocalized. Below given are resonating structures of $N{{O}_{2}}$

In case of${{N}_{2}}{{O}_{5}}$, it has two double bonded oxygens and one bridge oxygen and two single bonded oxygen. These two double bonds are localized among four oxygens. Below given are resonating structures of ${{N}_{2}}{{O}_{5}}$

So, the $N{{O}_{2}}$has two resonating structures and ${{N}_{2}}{{O}_{5}}$ has 3 resonating structures

Note: So, while drawing resonating structures you should be careful about lone pairs and charges. Here all double bonds partially exist. And oxygen has partial negative charge.
