arsenic group
Noun: - The univalent group derived from arsine: In chemistry, this term refers to a specific functional group or radical with the formula -AsH₂, which is derived from the compound arsine (AsH₃) by the removal of one hydrogen atom. It represents a univalent (having a valence of one) arsenic-containing group.
This is a highly specialized term used almost exclusively in the context of inorganic and organometallic chemistry to describe a specific molecular fragment. - The compound features an arsenic group bonded to the organic chain. - Researchers studied the reactivity of the arsenic group in various organoarsenic compounds.
- In Nomenclature: The term is used in systematic chemical naming to indicate the presence of the -AsH₂ moiety within a larger molecule.
- As a Ligand: In coordination chemistry, the arsenic group can act as a ligand, bonding to a central metal atom.
- Arsine (noun): The parent hydride compound, AsH₃, from which the group is derived.
- Arsonium (noun): A positively charged ion containing arsenic, such as [R₄As]⁺.
- Arsanyl (noun): An alternative systematic name for the H₂As- group; the "arsenic group" is a common name for this fragment.
- Arsanyl group: A more systematic synonym based on modern chemical nomenclature.
- -AsH₂ group: A formula-based synonym used in structural descriptions.
This term has no other common meanings outside of its specific use in chemistry. It should not be confused with the periodic table group containing arsenic (Group 15 or the nitrogen group), which is a different concept.
