Vedclass · Answer

(A) According to Fajan's rule,the covalent character of a compound increases with an increase in the oxidation state of the metal cation.In the $+4$ oxidation state,the metal ion has a smaller size and a higher charge density,which leads to greater polarizing power.Consequently,$MCl_4$ exhibits more covalent character,whereas $MCl_2$ exhibits more ionic character.Therefore,$MCl_2$ is more ionic than $MCl_4$.

$A$ metal,$M$,forms chlorides in its $+2$ and $+4$ oxidation states. Which of the following statements about these chlorides is correct?
