Pseudohalide ions and pseudohalogens There are certain monovalent negative ions made up of two or more electronegative atoms which exhibit properties similar to those of halide ions. Such ions are known as pseudo halide ions. Just as halide ions, pseudohalide ions have also corresponding dimeric molecules. These are called pseudohalogens and have properties similar to those of halogens.

Which among the following does not form polyhalide ion?
1 Chlorine
2 Bromine
3 Iodine
4 Fluoride
Explanation:
When the halide ions combine with halogen molecules or interhalogen, univalent ions are obtained. These are known as polyhalide ions. Among the given options, F doesn't form polyhalide ion because it doesn't have d-orbitals and cannot show higher oxidation state.
