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.

For reproduction of material from PPS: Their absence has been speculatively attributed to the extreme reactivity of such compounds, including the reaction of an initially formed fluoride with the walls of the glass container to form a non-volatile product.

C Chlorine fluoride Chlorine monofluoride Chlorine pentafluoride Chlorine trifluoride. BrF has not been obtained pure and dissociates into the trifluoride and free bromine. Each stage passes a slightly more concentrated product to the next stage and returns a slightly less concentrated residue to the previous stage. Information about reproducing material from RSC articles with different licences is available on our Permission Requests page.


Iodine pentafluoride IF 5 is a Colorless liquid, made by reacting iodine pentoxide with fluorine, or iodine with silver fluoride.

The authors called the effect “puzzling”, admitting they had expected formation of a volatile fluoride. The interhalogens of form XY have physical properties intermediate between those of the two parent halogens. For instance, ClF has a bond length of 1. What’s more, as it has 7 valence electrons, it can just frame one bond.

Beyond that, iodine monochloride has several applications, including helping to measure the saturation of fats and oils, and as a catalyst for some reactions.

All interhalogens are diamagnetic. In chlorine trifluoride, chlorine, the central atom has seven electrons in the valence shell. Diatomic Interhalogens AX The interhalogens of form XY have physical properties intermediate between those of the two parent halogens.


BrF 5 is too reactive to generate fluorine. Interhalogens containing fluorine are more likely to be volatile than interhalogens containing heavier halogens. How are interhalogen compounds formed? Primary amines react with iodine pentafluoride to form nitriles after hydrolysis with water.

This compound is the only interhalogen compound possible where the larger atom is carrying seven of the smaller atoms. The interhalogens of form XY have physical properties intermediate between those of the compounfs parent halogens. Retrieved from ” https: Some properties of interhalogen compounds are listed below.


Interhalogen compounds and polyhalides A. Made by direct combination of the elements to form a dark red crystalline solid.

The halogens react with each other to outline interhalogen compounds. The first page of this article is displayed as the abstract. Similarly, in BrF 5the four equatorial fluorine atoms are not in the same plane as integhalogen bromine atom though they are in the same plane as each other due to the extra repulsion from the lone pair compared to the axial bond pair. It is made by reacting the pentafluoride with fluorine.

All combinations of fluorine, chlorine, bromine, and iodine that have the above-mentioned general formula are known, but not interhaloyen are stable. It has the same molecular shape as chlorine trifluoride.
