Bromine trifluoride and IFS are formed by the reaction of X2 with AgF in HF to give AgX plus XF, followed by disproportionation of XF, but the products are not easily purified. Iodine trifluoride is a yellow powder obtained by fluorination of I2 in Freon at -78°C it decomposes to I2 and IF5 above -35°C. 

Several computational stmctural studies of iodine trifluoride have been published [11-16]. According to ab initio calculations [16], IF3 has a distorted T-shaped geometry with the axial I—F bond distance of 1.971 A, the equatorial 1—Fbond distance of 1.901 A and an Fax—I—Feq angle of 81.7°. 

The chemical properties of iodine trifluoride are almost unknown. IF3 forms 1 1 complexes with pyrazine or 2,2 -bipyridyl and reacts with CsF in a 1 3 molar ratio to give CS3IF6 [8]. The ligand exchange reaction of IF3 with trifluoroacetic anhydride leading to iodine(III) trifluoroacetates has been reported [17]. 

Write equations representing the hydrolysis of iodine trifluoride, pentafluoride, and heptafluoride. 

Describe the bonding in the iodine trifluoride molecule. Apply the VSEPR rule that lone pairs require more space than bonding pairs of electrons and are therefore placed in equatorial rather than axial positions.
