The nomenclature of BCl₃ is Boron trichloride.
Understanding the Nomenclature of BCl₃
BCl₃, known systematically as Boron trichloride, is a chemical compound formed between boron (a nonmetal) and chlorine (a nonmetal). Its name follows the rules for naming binary covalent compounds, which typically involve prefixes to indicate the number of atoms of each element.
Systematic Naming Explained
When naming binary covalent compounds like BCl₃, the following rules are applied:
- First Element: The first element in the formula is named first using its full element name. If there is only one atom of this element, the prefix "mono-" is usually omitted. In BCl₃, Boron is the first element, and since there's only one boron atom, no prefix is used.
- Second Element: The second element is named by taking the root of the element's name and adding the suffix "-ide". A prefix is then added to indicate the number of atoms of this element. For BCl₃, chlorine becomes chloride, and since there are three chlorine atoms, the prefix "tri-" is used.
This leads to the name Boron trichloride.
