As another difference, chlorine has a significant chemistry in positive oxidation states while fluorine does not. Chlorination often leads to higher oxidation states than bromination or iodination but lower oxidation states than fluorination. Chlorine tends to react with compounds including M–M, M–H, or M–C bonds to form M–Cl bonds. [40]
Chlorine and oxygen can bond in a number of ways: chlorine monoxide radical, ClO•, chlorine (II) oxide radical; chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical; chlorine dioxide, ClO 2, chlorine (IV) oxide; chlorine trioxide radical, ClO 3 •, chlorine (VI) oxide radical; chlorine tetroxide radical, ClO 4 •, chlorine (VII ...
However, the heavier halogens' p electron orbitals partly mix with those of d orbitals, which results in an increased effective bond order; for example, chlorine has a bond order of 1.12. [11] Fluorine's electrons cannot exhibit this d character since there are no such d orbitals close in energy to fluorine's valence orbitals. [11]
This process occurs naturally in plants photosystem II to provide protons and electrons for the photosynthesis process and release oxygen to the atmosphere, [1] as well as in some electrowinning processes. [2] Since hydrogen can be used as an alternative clean burning fuel, there has been a need to split water efficiently.
In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential ...
Perchloryl fluoride is produced primarily by the fluorination of perchlorates. The initial syntheses in the early 1950s used fluorine gas or fluorides and anodic oxidation as the fluorinating agents, but these give explosive gaseous mixtures. [8] A common fluorinator in modern syntheses is antimony pentafluoride: [3]: 372–373 ClO − 4 + 3 HF ...

Chloride can be oxidized but not reduced. The first oxidation, as employed in the chlor-alkali process, is conversion to chlorine gas. Chlorine can be further oxidized to other oxides and oxyanions including hypochlorite (ClO −, the active ingredient in chlorine bleach), chlorine dioxide (ClO 2), chlorate (ClO − 3), and perchlorate (ClO − 4).
