Question

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 ionic than $MC{l}_4$
• B. $MC{l}_2$ is more easily hydrolysed than $MC{l}_4$
• C. $MC{l}_2$ is more volatile than $MC{l}_4$
• D. $MC{l}_2$ is more soluble in anhydrous ethanol than $MC{l}_4$

Answer 1

The correct option is A $MC{l}_2$ is more ionic than $MC{l}_4$

$MC{l}_2$ is more ionic than $MC{l}_4$

Because according to Fajan's rule, compounds of metal in lower oxidation state are more ionic than those in a higher state.
