Vedclass · Answer

(D) According to Fajan's rule,the covalent character of a compound increases with an increase in the oxidation state (charge) of the metal cation.Given that the oxidation states $x$ and $y$ differ by two units,let us assume $x Since $y > x$,the compound with oxidation state $y$ will have more covalent character,and the compound with oxidation state $x$ will have more ionic character.Therefore,if $x Thus,both statements $(b)$ and $(c)$ are correct.

An element of the $3d-$ transition series shows two oxidation states $x$ and $y$,which differ by two units. Then:
