(b) It is also known as the anhydride of nitric acid

(c) It exists as a colourless solid below 273K

(d) The oxidation state of nitrogen is +5

I got this question in homework.

I would like to ask this question from P-Block Elements topic in portion P-Block Elements of Chemistry – Class 12

Answer 1

The correct option is (a) It is basic in nature

The explanation: Dinitrogen pentoxide (N2O5), also known as nitrogen (V) oxide or anhydride of nitric acid, is an oxide of nitrogen which is acidic in nature. The oxidation state of nitrogen in it is +5. It exists as a solid below 273K and decomposes to form nitrogen dioxide, nitric oxide and oxygen above a temperature of 273K.
