Question

The ${N_2}{O_5}$ is said to be ionic in solid state. Write the cation and anion in it and the hybridised state of $N$ atom in cation.
(a) $s$
(b) $sp$
(c) $s{p^2}$
(d) $s{p^3}$

Answer 1

Hint : ${N_2}{O_5}$ is a chemical named as Dinitrogen pentoxide which is having two nitrogen atoms and five oxygen atoms covalently bonded which is also known as nitrogen pentoxide or nitric anhydride.

Complete Step By Step Answer:
First of all, we will define the terms cations and anions.
Cations: Cations are the ions, in which the atoms or groups are having positive charges.
Anions: Anions are the ions, in which the atoms or groups are having negative charges.
Now, we moving forward the definition of ionic solids:
Ionic solids: The solids which are having cations and anions which are held by the strong electrostatic forces.
The ${N_2}{O_5}$ is a chemical named as Dinitrogen pentoxide which is having two nitrogen atoms and five oxygen atoms covalently bonded which is also known as nitrogen pentoxide or nitric anhydride.
The cation of the ${N_2}{O_5}$ is $N{O_2}^ +$ and the anion of the ${N_2}{O_5}$ is $N{O_3}^ -$ .
The cation of the ${N_2}{O_5}$ is $N{O_2}^ +$ , the $N$ is having $sp$ hybridised with the two bonded pairs.
Similarly, the anion of the ${N_2}{O_5}$ is $N{O_3}^ -$ , the $N$ is having $s{p^2}$ hybridised with the three bonded pairs.
Hence, the cation of the ${N_2}{O_5}$ is $N{O_2}^ +$ and the anion of the ${N_2}{O_5}$ is $N{O_3}^ -$ and the hybridised state of $N$ atom in cation in $sp$ hybridised due to the two bonded pairs.
Hence, the correct option is (b) $sp$ .

Note :
Ionic solids are the solids which are having cations and anions which are held by the strong electrostatic forces. As they are held by strong attraction forces, the ionic solids are hard and brittle in nature and also have high melting points.
