    A metal, M forms chlorides in its +2 and +4 oxidation states. Which of the following statements about these chlorides is correct?     AIEEE  Solved  Paper-2006

    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 the covalent characteristics. Hence,\[MC{{l}_{4}}\]is more covalent and\[MC{{l}_{2}}\]is more ionic.
