what is the most stable resonance structure if nitrogen is the central atom in the cno– ion?

Sagot :

The most stable resonance structure if nitrogen is the central atom in the CNO⁻ ion is seen in the first structure in the image attached below.

Resonance structures show the different forms of lewis structure in which a compound can exist whether as a stable resonance or an unstable resonance. It also explains the electronic bonding existing in a polyatomic compound with its bonds and charges.

The structure carrying the negative charge on the most electronegative atom is the most stable structure in resonance structures.

In the given compound CNO⁻, the lewis structure in which the resonance can exist is shown in the image attached below.

The first structure is the most stable because the negative charge is on the most electronegative element (oxygen).

The second structure has a (-2) oxidation state with two non-bonding electron pairs.

The third structure has a positive oxidation charge the electronegative oxygen which also makes it unstable.
