Which statements about corrosive sublimate (HgCl2) are correct? — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Transition metals exhibit their highest oxidation states in compounds with the most electronegative elements. Step 2: Oxygen (O) and Fluorine (F) are the two most electronegative elements in the periodic table. They can stabilize high oxidation states because of fluorine's high electronegativity (forming covalent/ionic bonds) and oxygen's ability to form multiple bonds (like in MnO4^- or CrO3). Step 3: Therefore, the highest oxidation states are found in combination with Fluorine (F) and Oxygen (O), matching option (a).
