Resonating Structures of HN3 and NaN3

Resonating Structures
Resonating structures are the various possible structures that can be drawn for a molecule by moving electrons around. These structures are used to represent the true electronic structure of a molecule in a more accurate way.

HN3
HN3 is hydrogen azide or hydrazoic acid. The Lewis structure of HN3 shows that it contains three N atoms, each with a lone pair of electrons and one H atom attached to one of the N atoms. The total number of possible resonating structures for HN3 can be calculated using the following steps:

1. Move a lone pair of electrons from one N atom to form a double bond with the adjacent N atom.
2. Move a single bond pair of electrons from the adjacent N atom to form a double bond with the central N atom.
3. Move a lone pair of electrons from the central N atom to form a double bond with the adjacent N atom.

By following these steps, three possible resonating structures of HN3 can be drawn.

NaN3
NaN3 is sodium azide. The Lewis structure of NaN3 shows that it contains three N atoms, each with a lone pair of electrons, one Na atom attached to one of the N atoms, and a triple bond between the other two N atoms. The total number of possible resonating structures for NaN3 can be calculated using the following steps:

1. Move a lone pair of electrons from one N atom to form a double bond with the adjacent N atom.
2. Move a single bond pair of electrons from the adjacent N atom to form a double bond with the central N atom.
3. Move a lone pair of electrons from the central N atom to form a double bond with the adjacent N atom.

By following these steps, three possible resonating structures of NaN3 can be drawn.

Combined Total
The total number of possible resonating structures of HN3 and NaN3 is the sum of the resonating structures for each molecule, which is 3 + 3 = 6.
