Aryl halides*1) with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a ...

PREPARATIVE experiments involving halogen substitution in mixed halides of silicon 1 have emphasized the need for obtaining some comparative measure of the ease of replacement of halogen atoms in ...

The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.

The replacement of hydrogen atom(s) in hydrocarbon, aliphatic or aromatic compounds, by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene), respectively.
