Question

Which of the following oxides is most acidic?

Options

A.Ag2O
B.V2O5
C.CO
D.N2O5

Solution

The oxide with the highest possitive oxidation state on the element other than Oshould 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.
