Assuming acid strength relates directly to number of O atoms bonded to the central atom, rank H₂N₂O₂ [or (HON)₂]; HNO₃ (or HONO₂
Elenna [48]

For Less number of oxygen atoms will be less acidic. Therefore, the rank will be.... So there is 1 oxygen atom bonded to each of the 2 nitrogen atoms.

For HNO3 or {HONO}2. So there are 3 oxygen atoms bonded to the nitrogen.

For HNO2 or HONO. So there are 2 oxygen atoms bonded to the nitrogen.

Less number of oxygen atoms will be less acidic. Therefore, the rank will be...

HNO3>HNO2>H2N2O2

Acid strength is the tendency of an acid, symbolized by the chemical formula, to dissociate into a proton, and an anion, The dissociation of a strong acid in solution is effectively complete, except in its most concentrated solutions.

The strength of a weak organic acid may depend on substituent effects. The strength of an inorganic acid depends on the atom’s oxidation state to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in an aqueous solution but is a weak acid when dissolved in glacial acetic acid.
