Q.49 The halides of transition elements become more covalent with increasing oxidation state of the metal. Why?
Thinking Process
This problem is based on concept ofFajan’s rule and its application.
NEETprep Answer: As the oxidation state increases, size of the ion of transition element decreases. As per Fajan’s rule, as the size of metal ion decreases, covalent character of the bond formed increases.
Therefore, the halide of transition elements become more covalent with increasing oxidation state of the metal.
