Vedclass · Answer

(D) The oxidation state of a metal in a compound is considered fractional if it represents the average oxidation state of multiple atoms of the same element in different oxidation environments within the same molecule.$Fe_3O_4$ is a mixed oxide of $FeO$ and $Fe_2O_3$,where $Fe$ exists in $+2$ and $+3$ states. The average oxidation state is $+8/3$.$Mn_3O_4$ is a mixed oxide of $MnO$ and $Mn_2O_3$,where $Mn$ exists in $+2$ and $+3$ states. The average oxidation state is $+8/3$.$Pb_3O_4$ is a mixed oxide of $2PbO$ and $PbO_2$,where $Pb$ exists in $+2$ and $+4$ states. The average oxidation state is $+8/3$.In $Na_2S_4O_6$ (sodium tetrathionate),the sulfur atoms are not metals. The question asks for a metal. However,if we evaluate the oxidation states of the metals provided in the options,all $Fe$,$Mn$,and $Pb$ in these specific mixed oxides show fractional average oxidation states. Given the options,$Na_2S_4O_6$ is the only compound where the central element $(S)$ is a non-metal,and the metal $(Na)$ is in a fixed $+1$ oxidation state.

Which metal in the following compounds is not present in a fractional oxidation state?
