Unformatted text preview: Chemistry 1000 Lecture 22: The halogens and the noble gases Marc R. Roussel Interhalogen compounds I There is a rich chemistry of interhalogen compounds and complex ions, i.e. compounds and ions made of two different halogens. I Several compounds are well known: XY XY 3 XY 5 XY 7 ClF ClF 3 ClF 5 BrF BrF 3 BrF 5 IF 3 IF 5 IF 7 BrCl ICl ICl 3 IBr Exercise: oxidation states and VSEPR geometries of these compounds I Made by a variety of synthetic routes, some less than obvious: Cl 2(g) + 3F 2(g) > 200 C----- 2ClF 3(g) Cl 2(g) + ClF 3(g) > 250 C----- 3ClF (g) KCl (s) + 3F 2(g) 200 C--- KF (s) + ClF 5(s) I Extremely powerful oxidizing agents: RCH 2 OH + BrCl HCl + HBr + RCOOH I ClF 3 is used as a cleaning agent in chemical vapor deposition chambers. I Most halogen fluorides are amphoteric. I ClF 3 acting as a Lewis acid:- :F: .. .. F: Cl :F: :F: :F . . . . Cl :F: :F: :F . . . ....
