Also in anhydrous conditions,silver reacts with fluorine and forms silver difluoride and cobalt gives cobalt(III)fluoride,these metals showing higher oxidation states than is usual in their simple salts.
Chlorine has a lower electrode potential and electronegativity than fluorine but will displace bromine and iodine from aqueous solutions of bromide and iodide ions respectively:
Chlorine reacts directly with carbon monoxide to give carbonyl chloride(phosgene):
and sulphur dioxide to give sulphur dichloride dioxide:
