Vedclass · Answer

(D) Stock notation represents the oxidation state of a metal in a compound using Roman numerals in parentheses.In $Hg_2Cl_2$,the oxidation state of $Hg$ is $+1$,so it is $Hg(I)Cl$. In $HgCl_2$,the oxidation state of $Hg$ is $+2$,so it is $Hg(II)Cl_2$.Option $A$ and $B$ are correct because $Hg(I)$ is the reduced form of $Hg(II)$.Option $C$ is correct as stock notation explicitly states the oxidation state.Option $D$ is incorrect because 'Aurous' refers to $Au(I)$,whereas $Au(III)Cl_3$ is 'Auric chloride'. Therefore,$Au(III)Cl_3$ is not Aurous chloride.
