Answer 2

Answer:

The oxide of nitrogen existing in solid state at room temperature is N₂O₅.

Therefore, the option (4) is correct.

Explanation:

Nitrogen has six different types of oxides with oxidation state from +1 to +5.

N₂O, NO, N₂O₃, NO₂, N₂O₄ and N₂O₅.

• NO is nitrogen monoxide in which nitrogen is present in +2 oxidation state. It is colorless gas at room temperature. It is slightly heavier than air.

• NO₂ and N₂O₄ are both present in +4 oxidation state. They both exist in equilibrium at room temperature. NO₂  is a reddish brown gas at room temperature.

• In nitrous oxide N₂O, nitrogen present in +1 oxidation state. It is a colorless gas with faint pleasant smell.
• In N₂O₅, nitrogen is present in +5 oxidation state. N₂O₅ exists as white crystalline solid at room temperature.
