Covalent Nomenclature
This document discusses the rules for naming binary covalent compounds. Binary covalent compounds are composed of two non-metal elements that share electrons. The first element is named first using its full name, while the second element name has the ending dropped and replaced with -ide. Prefixes are used to indicate the number of atoms present and are not used with the first element name except for mono-. Examples are provided such as boron trifluoride (BF3) and carbon trichloride (CCl3).

Covalent Nomenclature
- 1. Nomenclature of CovalentCompounds Friday November 7th, 2008
- 2. Binary Covalent CompoundsCompounds that have two elements (binary) Are the combination of two non-metals Electrons are SHARED, so don’t worry about balancing charges
- 3. Rules for NamingBinary Covalent Compounds The first element is named first, using the full name of the element The second element is named by dropping the ending and adding the suffix -ide Prefixes are used to denote the numbers of atoms present (the subscripts indicate the numbers of atoms present) The prefix mono - is never used for the first element, only the second
- 4. Prefixes Prefix NumberIndicated Mono- 1 Di- 2 Tri- 3 Tetra- 4 Penta- 5 Hexa- 6 Hepta- 7 Octa- 8 Nona- 9 Deca- 10
- 5. How do Iname them? Example: BF 3 Boron trifluoride The names is binary (two names)
- 6. Try these… NOCO 2 N 2 O 5 CO CCl 3
