WebThis page looks at ways of swapping the -OH group in the -COOH group of a carboxylic acid for a chlorine atom. This produces useful compounds called acyl chlorides (acid chlorides). It covers the use of phosphorus(V) chloride and phosphorus(III) chloride as well as sulphur dichloride oxide (thionyl chloride). Replacing -OH by -Cl. Introduction WebIn the cases of chlorine and bromine, the iron atoms are oxidised to iron(III) ions. Electrons are removed by the chlorine or bromine.
