A metal, M from chaloride in its `+2` and `+4` oxidation states . Which of the following statement about thes chalorides is correct ?

Options

A. `MCl_(2)` is more soluble in anhydrous ethanol than `MCl_(4)`
B. `MCl_(2)` is more volatile than `MCl_(4)`.
C. `MCl_(2)` is more easily hydrolyzed than `MCl_(4)`.
D. `MCl_(2)` is more ionic than `MCl_(4)`.

Answer

D

Explanation

In general, lower oxidation states are less polarizing than higher oxidation states. Thus, `MCl_(2)` is less covalent and more ionic than `MCl_(4)`. Thus, `MCl_(4)` is more easily hydrolyzed, more volatile, and more soluble in `C_(2)H_(5)OH` than `MCl_(2)`.
