tetrahalide
Definition
Noun: A chemical compound that is a halide containing exactly four halogen atoms in each of its molecules.
Usage
A "tetrahalide" is a specific type of halide compound. The term is used primarily in chemistry to classify and describe molecules where a central atom or group is bonded to four halogen atoms (fluorine, chlorine, bromine, or iodine).
Examples
- Carbon tetrachloride (CCl₄) is a well-known tetrahalide.
- The synthesis of a silicon tetrahalide was described in the paper.
- Zirconium tetraiodide (ZrI₄) is an example of a metal tetrahalide.
Advanced Usage
- The prefix "tetra-" explicitly denotes the quantity four. Therefore, the term is used for precise molecular description, distinguishing it from dihalides (two halogens) or trihalides (three halogens).
- It can refer to both covalent molecular compounds (e.g., CCl₄) and ionic network solids, depending on the elements involved.
Variants and Related Words
- Halide (n): A binary compound in which one part is a halogen atom.
- Tetrafluoride (n): A tetrahalide where all four halogen atoms are fluorine (e.g., sulfur tetrafluoride, SF₄).
- Tetrachloride (n): A tetrahalide where all four halogen atoms are chlorine (e.g., carbon tetrachloride, CCl₄).
- Tetrabromide (n): A tetrahalide where all four halogen atoms are bromine.
- Tetraiodide (n): A tetrahalide where all four halogen atoms are iodine.
Synonyms
- There is no direct single-word synonym. The term is a precise technical descriptor. A descriptive phrase could be "quadruple halide" or "four-atom halide compound," but these are not standard terminology.
Related Phrases/Concepts
- Coordination number: In a tetrahalide, the central atom often has a coordination number of four.
- Tetrahedral geometry: Many molecular tetrahalides, like CCl₄, have a tetrahedral molecular shape due to four bonding pairs of electrons.
Noun
-
any halide containing four halogen atoms in its molecules
