Interhalogen compounds All are of the type XX’ n where n = odd nos. X’ is always the lighter halogen since the smaller halogen X’ are bonded around the larger X. As the ratio of the radius of X to that of X’ increases, n also increases. IF 7 IF 5 ICl 3 IClIBr BrF 5 BrF 3 BrClBrI ClF 3 ClF
Preparation The interhalogen compounds can be prepared by direction combination or by the action of halogen on lower interhalogen compounds. The product formed depends upon some specific conditions For example:
Properties Some properties of interhalogen compounds are given in Table:
Uses These compounds can be used as non aqueous solvents. Interhalogen compounds are very useful fluorinating agents. ClF 3 and BrF 3 are used for the production of UF 6 in the enrichment of 235 U. U(s) + 3ClF 3 (l) → UF 6 (g) + 3ClF(g
