Which among the following does not form polyhalide ions?a)Chlorineb)B...
Polyhalide ions are formed by combining halide ions with a halogen molecule. They are negatively charged ions and are commonly used in organic chemistry as reagents. However, not all halogens can form polyhalide ions.
Explanation:
Halogens are a group of elements that include fluorine, chlorine, bromine, iodine, and astatine. These elements have similar chemical properties and can form polyhalide ions by combining with halide ions.
Chlorine, bromine, and iodine can form polyhalide ions by reacting with halide ions. For example, chlorine can form Cl3- and Cl5- ions by reacting with chloride ions. Similarly, bromine can form Br3- and Br5- ions by reacting with bromide ions, and iodine can form I3- and I5- ions by reacting with iodide ions.
However, fluorine cannot form polyhalide ions because it is too reactive and can easily oxidize the halide ions to form fluoride ions. Fluoride ions are more stable than polyhalide ions, and hence, fluorine does not form polyhalide ions.
In summary, among the given options, fluorine does not form polyhalide ions. This is because fluorine is too reactive and can easily oxidize the halide ions to form fluoride ions, which are more stable.
