From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. They also asserted that a positively charged halogenatom is isoelectronic with oxygen and that carbon and bromine have comparable ionization potentials.

The resulting radicals abstract hydrogen from tributyltin hydride to a tributyltin radical which in turn abstracts the halogenatom to form an alkyl radical. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As compared to hydrogen bonding, the halogenatom takes the place of the partially positively charged hydrogen as the electrophile. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. What differentiates a halogenated ether from other types of ethers is the substitution (halogenation) of one or more hydrogen atoms with a halogenatom. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Haloalcohols, especially chloroalcohols and bromoalcohols (in which the halogenatom is chlorine or bromine, respectively) are typically synthesized by halogenation of alkenes in the presence of water or an alcohol.

This polarity can be reversed when a primary or secondary amine is substituted with a good leaving group (such as a halogenatom or an alkoxy group). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This can be further subdivided into two types of reaction processes, the first of which, hydrogenolysis, is the replacement of the halogenatom with a hydrogen atom. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The reaction of the alkyl nitrite with an aromatic amine in a halogenated solvent produces a radical aromatic species, this then abstracts a halogenatom from the solvent. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thus, the rare gas halide molecules are formed by an ionic bond since the excited electron of the noble gas is partly transferred to the halogenatom.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, the standard method for removing halogen atoms requires the use of stoichiometric organotin reagents, such as tributyltin hydride.
