उत्तर
Some mononegative ions made up of two or more electronegative atoms behave in the same way as the halide ions do. Such ions are referred to as pseudo halide ions.
Examples: ,
Pseudo halogens are diatomic compounds that exhibit halogen-like characteristics. Examples of pseudo halide ions and pseudo halogens include the following:
| Pseudo halide ions | Pseudo halogens |
| Cyanide (CN−) | Cyanogen (CN)2 |
| Cyanate (OCN−) | Oxycyanogen (OCN)2 |
| Thiocyanate (SCN−) | Thiocyanogen (SCN)2 |
| Selenocyanide (SeCN−) | Selenocyanogen (SeCN)2 |
