Explanation:
Pseudo halides are ions that have similar chemical properties to halide ions (such as chloride, bromide, and iodide) but are not actually halides. They typically have a negative charge and contain a central atom bonded to one or more electronegative atoms.
In the given options, CNO-, CN-, and SCN- are all examples of pseudo halide ions because they exhibit similar chemical properties to halides. However, S2- is not a pseudo halide ion.
The reason S2- is not a pseudo halide ion is because it does not have similar chemical properties to halide ions. Unlike halides, which are typically good nucleophiles and are often used in substitution reactions, S2- is a strong reducing agent and is not commonly involved in substitution reactions.
S2- is a reducing agent because it can easily gain two electrons to form S2-, which has a filled valence shell. This makes it a good reducing agent in redox reactions. In contrast, halides are not strong reducing agents because they have a filled valence shell and do not readily gain electrons.
Additionally, S2- does not have the same size or electronegativity as halide ions. Halides (such as Cl-, Br-, and I-) have larger atomic radii and lower electronegativities than sulfur (S). This difference in size and electronegativity affects their chemical properties and reactivity.
In summary, S2- is not a pseudo halide ion because it does not exhibit the same chemical properties as halide ions and has different size and electronegativity characteristics.
