Question

What are the uses of interhalogen compounds?

Answer 1

The uses of interhalogen compounds are as follows :

• ICl is used as a halogenating agent and also in the estimation of iodine number of fats and oils. 
• In the preparation of polyhalides, interhalogen compounds are used.
• ClF₃ and BrF₃ are widely used as fluorinating agent. They are used in the separation of ²³⁵U isotope by fluorinating. 

 ²³⁵U_(s) + 3ClF_3(I) - ²³⁵UF_6(g) + 3CIF_(g)

• In propellants ClF₃  and IF₃ are used as oxidisers.
• They are used as non-aqueous solvents.
• The XX’ interhalogen compounds are used as a catalyst for the oxidation of As(III)
