Transition metals usually exhibit highest oxidation states in their (a) chlorides (b) fluorides (c) bromides (d) iodides

Transition metals usually exhibit highest oxidation states in their_________.

(a) chlorides

(b) fluorides

(c) bromides

(d) iodides

Expert Solution

Answer : (b) fluorides

Explanation :

The highest oxidation states of any transition metals are shown by fluorides and oxides. As fluorine and oxygen are the most electronegative elements in periodic table. The highest oxidation state shown by any transition metal is +8 and the element which shows +8 oxidation state are Ruthenium (Ru) and Os(Osmium).

b) fluorides
