Tungsten tetrabromide (WBr4) and tungsten tetrachloride (WCl4) have significant differences in redox properties.
For tungsten tetrabromide, the bromine atom has a high electronegativity, which makes the electron cloud on the bromine atom shift to the tungsten atom, making the electron cloud density of the tungsten atom relatively low. This shift in electron cloud density makes it easier for the electrons of tungsten atoms to be taken away by oxidants, so tungsten tetrabromide exhibits certain reductivity. In a specific oxidizing environment, the oxidation state of the tungsten atom of tungsten tetrabromide can be increased from +4 to +6, which indicates that tungsten tetrabromide can be oxidized to a compound with a higher oxidation state under the action of an appropriate oxidizing agent.
In contrast, the molecular structure of tungsten tetrachloride (WCl4) is similar to that of tungsten tetrabromide, in that tungsten atoms are covalently bonded to four chlorine atoms to form a tetrahedral structure. However, chlorine atoms are less electronegative than bromine atoms, which makes the electron cloud density on chlorine atoms relatively high. This shift in electron cloud density makes it more difficult for the electrons of tungsten atoms to be captured by oxidants, so tungsten tetrachloride exhibits lower reducibility. In common redox reactions, the oxidation state of the tungsten atom of tungsten tetrachloride is usually kept at +4, and it is not easy to be oxidized to a compound with a higher oxidation state.
In practical applications, the difference in redox properties of tungsten tetrabromide and tungsten tetrachloride may affect their reactivity and application range in certain chemical reactions. For example, in some chemical reactions that require oxidation reactions, we may choose compounds with higher redox properties, such as tungsten tetrabromide, to promote the reaction and achieve specific chemical results. In some chemical reactions that need to maintain a lower oxidation state, we may be more inclined to choose compounds with lower redox properties, such as tungsten tetrachloride, to keep the reaction going and the stability of the product.
