Draw three resonance structures for N2O. This species has its three atoms bonded sequentially in the following fashion: N-O. Draw your resonance structures so that the atoms in them are bonded together in this order. Select the most important resonance structure for this species based on the formal charges on the atoms of the three resonance structures you have drawn. Now select the statement from the multiple choices which is true about this most important resonance structure. In the most important resonance structure of N2O :

Most important resonance structure of N₂O is

      N ≡ N⁺ ─ O⁻

Explanation:

Nitric oxide is an oxide of nitrogen known as laughing gas.

Center atom of N₂O is nitrogen have two sigma bonds and zero lone pair with Sp hybridisation having linear geometrical shape.

Now we can sketch the resonating structures of N₂O is as follows

Look the structure 1 , there are positive charge on central Nitrogen and negative charge on oxygen atom along the lone pair in the left side nitrogen atom. We know Electronegativity of oxygen is higher than nitrogen., it means negative charge stable on oxygen atom and positive charge on nitrogen atom.

Octet rule valid in structure 1

so, structure 1 is most stable as compare to others.

yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes

explanation:

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.
