We know that nitrogen can't have +5 oxidation state,so why N2O5 exists?

Expert Answer:
Actually, you are getting confused in covalency and oxidation state because they both are different things.
Covalency is the combining capacity of an atom.
In the case of nitrogen, it can form three covalent bond and one coordinate bond by its lone pairs which mean Nitrogen has covalency 4.
on the other hand, the oxidation state is the total charge present on an atom in its combined state.
In N2O5, nitrogen is attached to he five oxygen atoms which exert +5 charge on the nitrogen atom.
Hence its covalency is four and oxidation state in N2O5 is +5.

- pls explain
- why nitrogen have long range of oxidation state?
- Why NO does not dimerise even it has odd electron?
- Explain the structures of BCl3 and PH3 with the help of theory of hybridisation.
- A gas X is formed by heating ammonium nitrite. X can also be obtained by heating barium azide. Mg metal burns in X to form Y. Y reacts with water to form a gas zZwhich turns red litmus blue. Identify X,Y and Z. Write all the reactions involved.
- A gas is obtained by the reaction of magnesium nitride with water. It acts as a lewis base and turns red litmus blue. It reacts with CuO as a reducing agent. It is obtained from two elements by reacting at 700K and high pressure. It is highly soluble in water. It forms blue coloured solution with copper sulphate. Identify the gas and write all the reactions involved.

1) An unknown salt X react with hot conc.
to produce a brown coloured gass which intensifies on addition on copper turnings . on adding dilute ferrous sulphate olution to an aqueous solution to an aquaeous solution of X and then carefully adding conc.
