Vedclass · Answer

(C) The acidic character of non-metal oxides increases with the increase in the oxidation state of the central atom and the electronegativity of the central atom.$1$. Oxidation states: $N_2O_5 (+5)$,$SO_2 (+4)$,$CO_2 (+4)$,$CO (+2)$.$2$. $N_2O_5$ is the strongest acid because $N$ is highly electronegative and in its highest oxidation state $(+5)$.$3$. Comparing $SO_2$ and $CO_2$: $S$ is less electronegative than $C$,but $S$ is larger and can stabilize the negative charge better in the conjugate base,or by comparing their hydration products ($H_2SO_3$ vs $H_2CO_3$),$H_2SO_3$ is a stronger acid.$4$. $CO$ is a neutral oxide.$5$. Therefore,the correct order is $N_2O_5 > SO_2 > CO_2 > CO$.
