$As^{+5}$ salts are better oxidizing agents.

Vedclass · Answer

(D) According to the inert pair effect,the stability of the lower oxidation state is more dominant than that of the higher oxidation state. Therefore,$Tl^{+}$ is more stable than $Tl^{3+}$,making $Tl^{3+}$ salts strong oxidizing agents.In the case of gallium,$Ga^{3+}$ is more stable than $Ga^{+}$,so $Ga^{+}$ salts act as reducing agents.For lead,$Pb^{2+}$ is more stable than $Pb^{4+}$ due to the inert pair effect,making $Pb^{4+}$ salts strong oxidizing agents.For arsenic,which belongs to group $15$,the higher oxidation state $(+5)$ is generally more stable than the lower oxidation state $(+3)$ due to the absence of a significant inert pair effect compared to heavier elements. Thus,$As^{+5}$ is not a better oxidizing agent compared to the others mentioned.Hence,the statement in option $D$ is incorrect.
