Vedclass · Answer

(D) The acidity of oxides generally increases with an increase in the oxidation state of the central atom and with an increase in the electronegativity of the central atom.$Ag_2O$ is basic,$V_2O_5$ is amphoteric,$CO$ is neutral,and $N_2O_5$ is strongly acidic.In $N_2O_5$,the oxidation state of $N$ is $+5$ and $N$ has high electronegativity,which makes the $N-O$ bond more polar and the oxide more acidic compared to the others.
