Did you know that there are combinations of halogen compounds as well? They are the interhalogen compounds. They consist of two halogens. In this chapter. An interhalogen compound is a moleculewhich contains two or more different halogenatoms (fluorine, chlorine, bromine, iodine, or astatine) and no atoms of. Interhalogen Compounds are the subordinates of halogens. Compounds containing two unique sorts of halogens are termed as interhalogen compounds.

The halogens react with each other to outline interhalogen compounds. The compounds which are formed by the union of two different halogens are called inter halogen compounds.

Fluorine reacts with iodine pentafluoride at K to shape Iodine Heptafluoride. The crystal structure of iodine monochloride consists of puckered zig-zag chains, with strong interactions between the chains. To name an Interhalogen compound, the less electronegative element is placed on to the left in formulae and naming is done straight forward. Views Read Edit View history.

What’s more, as it has 7 valence electrons, it can just frame one bond. The covalent bond between the two atoms has some ionic character, the less electronegative element, X, being oxidised and having a partial positive charge.

Some combinations of astatine with other halogens are not even known, and those that are known are highly unstable. Most interhalogen compounds known are binary composed of only two distinct elements. It is possible to produce larger interhalogens, such as ClF 3by exposing compounvs interhalogens, such as ClF, to pure diatomic halogens, such as F 2. Interhalogen compounds and polyhalides A.


Structures The structures found for the various interhalogens conform interhalogdn what would be expected based on the VSEPR model.

It reacts with elements, oxides and carbon halides. The covalent bond between the two atoms has some ionic character, the larger element, X, becoming oxidised and having a partial positive charge. ClF 3 has been investigated as a high-performance storable oxidizer in rocket propellant systems.

An interhalogen compound is a molecule which contains two or more different halogen atoms fluorinechlorinebromineiodineor astatine and no atoms of elements from any other group. Ternary species are also formed, and the species can be neutral, cations or anions.

Bromine monofluoride BrF has not been obtained pure – it dissociates into the trifluoride and free bromine. If the material has been adapted instead of reproduced from the original RSC publication “Reproduced from” can be substituted with “Adapted from”.

Interhalogen – Wikipedia

Some interhalogens, especially those containing bromine, are liquidsand most iodine-containing interhalogens are solids.

Most of the interhalogen compounds contain fluorine: Interhalogen anions are also formed by reaction with halide ion donors, whereas interhalogen cations are formed by reaction with halide ion acceptors.

It reacts with many metals and metal oxides to form similar ionized entities; with some others it forms the metal fluoride plus free bromine and oxygen. By direct mixing of Halogens and by reaction of Halogens with lower Interhalogen compounds. There are never more than two types of halogen atoms in an interhalogen molecule.


It is highly reactive, even slowly with glass. Go to our Instructions for using Copyright Clearance Center page for details. Smaller interhalogens, such as ClF, can form by direct reaction with pure halogens.

It reacts violently with water and most metals and nonmetals. Not much is known about iodine trifluoride as it is so unstable. In addition, there exist analogous molecules involving pseudohalogenssuch as the cyanogen halides.

The central atom in Iodine heptafluoride has seven bond pairs which is why the shape is pentagonal bipyramidal shape. Iodine pentafluoride IF 5 is a colorless liquid, made by reacting iodine pentoxide with fluorine, or iodine with silver fluoride.

The interhalogens of form XY have physical properties intermediate between those of the two parent halogens.

All the interhalogens are violently hydrolyzed by water. The interhalogen IF 7 can be formed by reacting palladium iodide with fluorine.
