Question

Which among the following does not form polyhalide ion?

Options

• Chlorine

• Bromine

• Iodine

• Fluorine

Answer 1

Fluorine

Explanation:

Univalent ions are formed when halide ions react with halogen molecules or interhalogen. Polyhalide ions are what they're called. F is the only alternative that does not generate a polyhalide ion because it lacks d-orbitals and hence cannot display a higher oxidation state.
