Vedclass · Answer

(C) reducing agent is a substance that can be oxidized to a higher oxidation state. In $SO_2$,the oxidation state of $S$ is $+4$,which can be oxidized to $+6$. In $NO_2$,the oxidation state of $N$ is $+4$,which can be oxidized to $+5$. In $ClO_2$,the oxidation state of $Cl$ is $+4$,which can be oxidized to $+7$. In $CO_2$,the oxidation state of $C$ is $+4$,which is its maximum oxidation state (group valence). Therefore,$CO_2$ cannot be further oxidized and cannot act as a reducing agent.
