Question

Which of the following oxides is most acidic?

Solution

Correct option is

N2O5

The oxide with the highest positive oxidation state on the element other than O should be most acidic. Oxidation state of V in V2O5 and N in N2O5 are +5. But the electronegativity of N is higher, making N2O5 the most acidic oxide.
