Passage
When two different halogens react with each other, the compounds formed are called interhalogen compounds.
The general formula of these compounds is given by XX', 
, 
and 
.
Here, X = halogen of large size and more electropositive.
X' = halogen of smaller size and more electronegative,
e.g. CIF, ClF3, IF5, IF7, etc.
All are covalent and diamagnetic.
They are either volatile liquids or solids except CIF, BrF, CIF3, IF5 and IF7.
Interhalogen compounds are more reactive than halogens (except fluorine). The reason is X—X' bond in interhalogens is weaker than X—X bond in halogens (except F— F bond).
Hydrolysis of interhalogens Interhalogen compounds undergo hydrolysis giving halide ion derived from the smaller halogen and a hypohalite (when XX'), halite (when ), halate (when ) and perhalate (when ) n ion derived from the larger halogen.
XX' + H2O → HX + HOX
Q.
Which is more stable?
The general formula of these compounds is given by XX',
, and .Here, X = halogen of large size and more electropositive.
X' = halogen of smaller size and more electronegative,
e.g. CIF, ClF3, IF5, IF7, etc.
