Question

Among the following halogens, the one which does not form an oxyacid is:

Options

• Fluorine

• Chlorine

• Bromine

• Iodine

Answer 1

Fluorine

Explanation:

Fluorine is the most electronegative element and does not form oxyacids because it lacks d-orbitals and cannot expand its octet to form bonds with oxygen. On the other hand, chlorine, bromine, and iodine form various oxyacids such as HClO, HBrO, and HIO, where the halogen is in higher oxidation states.
