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.

Interhalogen Compounds

Chlorine monofluoride, chlorine, and tetrafluorosilane were formed. To name an Interhalogen compound, the less electronegative element is placed on to the left in formulae and naming is done straight forward.

It reacts more violently than fluorine, often explosively. Tetra-atomic Interhalogens AX 3 Chlorine trifluoride Compoudns 3 is a colorless gas which condenses to a green liquid, and freezes to a white solid. Journal of the American Chemical Society. Hypergolic means explode on contact with no need for any activator.

The halogens react with each other to form interhalogen compounds. The covalent bond between the two atoms has some ionic character, the larger element, X, becoming oxidised and having a partial positive charge.

Similarly, in BrF 5the four equatorial fluorine atoms are not in the same plane as the 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. The molecule has the form of a tetragonal pyramid.

It reacts with many metals and metal oxides to form similar ionised entities; with some others it forms the metal fluoride plus free bromine and oxygen. The covalent bond between the two atoms has some ionic character, the less electronegative halogen, X, being oxidised and having interhalkgen partial positive charge.


This method of production is especially useful for generating halogen fluorides. A halogen atom reacts with a lower interhalogen to frame another interhalogen compound.

Interhalogen – Wikipedia

Typically, interhalogen bonds are more reactive than diatomic halogen bonds—because interhalogen bonds are weaker than diatomic halogen bonds, except for F 2. The following 18 pages are in this category, out of 18 total.

B Bromine monochloride Bromine monofluoride Bromine pentafluoride Bromine trifluoride. Sulphur Allotropic Forms Sulphur: Wikimedia Commons has media related to Interhalogen compounds. These both make use of the volatility of UF 6.

The inter halogens are generally more reactive than halogens except F. For instance, ClF has a bond length of 1. It is physically stable, but compounss violently with water and most metals and nonmetals.

In addition, there exist analogous molecules involving pseudohalogenssuch as the cyanogen halides. Some interhalogens, especially those containing bromine, are liquidsand most iodine-containing interhalogens are solids. One of the aspects of the chemistry of fluorine is that it is so reactive that it can form compounds with the Noble Gases.

IF is unstable and decomposes at 0 C, disproportionating into elemental iodine and iodine pentafluoride. The main article for this category is Interhalogen.

Summary of the Known Interhalogens. U isotope separation is difficult because the two isotopes have very nearly identical chemical properties, and can only be separated gradually using small mass differences.

ICl 3 has the lowest. Unlike the other halogens, fluorine atoms have high electronegativity and small size which is able to stabilize them.


Ternary species are also formed, and the species can cpmpounds neutral, cations or anions. It is used in organic chemistry as a fluorinating agent. For reproduction of material from intethalogen other RSC journals and books: The interhalogen compounds of type AX and AX 3 are formed between the halogen having very low electronegative difference e. Authors contributing to RSC publications journal articles, books or book chapters do not need to formally request permission to reproduce material contained in this article provided that the correct acknowledgement is given with the reproduced material.

There are currently two generic commercial methods employed internationally for enrichment: They are all prone to hydrolysisand ionize to give rise to polyhalogen ions. This is on the grounds that an atom will dependably attempt and get to the condition of most minimal energy, for Hydrogen this implies either 2 electrons thusly finishing its 1s sub shell or 0 electrons.

XX is the XXth reference in the list of references.


The axial bond pairs bend interhqlogen the tropical position to minimize compounda repulsions due to lone pair- lone pair bonds.

Select Grade 6 7 8 9 10 11 12 12th pass. IF can be generated, by the following reactions: The molecule is a planar dimer, with each iodine atom surrounded by four chlorine atoms.
