Final answer:
The unique structure formed during molecular halogen addition is called an interhalogen compound. It is formed by the combination of different halogens. The discovery of interhalogens can be attributed to various scientists.
Step-by-step explanation:
The unique structure formed during molecular halogen addition is called an interhalogen compound. Interhalogens are compounds in which halogen atoms covalently bond to each other. They are formed by the combination of two or more different halogens, such as chlorine and bromine. The discovery of interhalogens can be attributed to different scientists. Eiji Osawa predicted a spherical form of interhalogens based on observations of a similar structure. Computational chemist Elena Galpern predicted a highly stable 60-carbon interhalogen molecule. Harold Kroto, working with Canadian radio astronomers, also contributed to understanding the nature of interhalogen compounds.
