B) $ MCl_2 $ is more easily hydrolysed than $ MCl_4 $
C) $ MCl_2 $ is more volatile than $ MCl_4 $
D) $ MCl_2 $ is more soluble in anhydrous ethanol than $ MCl_4 $
Show Answer
Answer:
Correct Answer: A
Solution:
Metal atom in the lower oxidation state forms the ionic bond and in the higher oxidation state the covalent bond because higher oxidation state means small size and great polarizing power and hence greater the covalent character. Hence $ MCl_2 $ is more ionic than $ MCl_4 $ .
