The interhalogen compounds can be prepared by the direct combination or by the action of halogen on lower interhalogen compounds. The product formed depends upon some specific conditions, For e.g.,
(dilutedwithwater)Br2+3F2→2BrF3
(excess)Br2+5F2→2BrF5
BrF5+3H2O→HBrO3+5HF
HBrO3 is bromic acid, hence, the salt is bromate. And interhalogen compound is called halate.
