What are the interhalogen compounds?Give examples.

Explanation

When two different halogens form a binary compound, it is known as interhalogen compound. Such compounds are formed due to the difference in the electronegativities of halogen atoms. The general formula of interhalogen compound is `AX_(n)`, where A is always bigger and X is smaller halogen atom and n = 1,3,5 or 7.They are covalent in nature. The maximum value of n for iodine is 7, bromine is 5 and chlorine is 3. Interhalogen compounds may be of the following types:
`AX" ""type":CIF,ICl," "AX_(3)" ""type":ClF_(3),BrF_(3)`
`AX_(5)" ""type":IF_(5),BrF_(5)," "AX_(7)" ""type":IF_(7)`
