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

    A) \[MC{{l}_{2}}\]is more volatile than \[MC{{l}_{4}}\]

    B) \[MC{{l}_{2}}\]is more soluble in anhydrous ethanol than\[MC{{l}_{4}}\]

    C)  \[MC{{l}_{2}}\]is more ionic than\[MC{{l}_{4}}\]

    D) \[MC{{l}_{2}}\]is more easily hydrolysed than\[MC{{l}_{4}}\]

    Correct Answer: C

    Solution :

     \[MC{{l}_{2}};\] oxidation state of \[M=+2\] \[MC{{l}_{4}};\]oxidation state of \[M=+4\] Higher the oxidation state, smaller the size. Greater the polarising power, greater is the covalent character. Hence,\[MC{{l}_{4}}\]is more covalent and\[MC{{l}_{2}}\]is more ionic.
