The interhalogen compound formed from the reaction of bromine with excess of fluorine isa :

CONCEPT:

• Interhalogen Compounds
  • Interhalogen compounds are formed when two different halogens react with each other.
  • The compounds formed depend on the ratios and specific halogens involved.
  • When bromine reacts with an excess of fluorine, it forms bromine pentafluoride (BrF₅).

EXPLANATION:

• When bromine (Br₂) reacts with an excess of fluorine (F₂), the product formed is bromine pentafluoride (BrF₅).

• Bromine pentafluoride is an interhalogen compound in which one bromine atom is bonded to five fluorine atoms.
• The name "perhalate" is used to describe compounds where the halogen is in its highest oxidation state, which fits for BrF₅.

Conclusion:

Therefore, The correct answer is perhalate.
