why interhalogen compounds are more reactive then related interhalogen compounds

Expert Answer:

Interhalogen compounds are formed by reactions between different halogens. All possible interhalogen compounds of the type XY are known. Bromine reacts with chlorine, for example, to give BrCl, which is a gas at room temperature.

Interhalogen compounds with the general formulas XY3, XY5, and even XY7 are formed when pairs of halogens react. Chlorine reacts with fluorine, for example, to form chlorine trifluoride.

ClF3 and BrF5 are extremely reactive compounds. ClF3 is so reactive that wood, asbestos, and even water spontaneously burn in its presence. These compounds are excellent fluorinating agents, which tend to react with each other to form positive ions such as ClF2+ and BrF4+ and negative ions such as IF2- and BrF6-.
