OTHER DISPLACEMENT AND OXIDATION REACTIONS.
Many of the reactions of halogens can be considered as either oxidation or displacement reactions;the redox potentials (Table 11.2)give a clear indication of thir relative oxidising power in aqueous solution. Fluorine,chlorine and bromine have the ability to displace hydrogen from hydrocarbons,but in addition each halogen is able to displace other elements which are less electronegative than itself. Thus fluorine can displace all the other halogens from both ionic and covalent compounds for example.
and oxygen from water and silica
