Study Notes
Naming Binary Molecular Compounds
- Composed of two nonmetallic elements.
- Names typically end in -ide.
Use of Prefixes
- Prefixes indicate the number of atoms for each element in the compound.
- Common prefixes include:
- Mono- (1)
- Di- (2)
- Tri- (3)
- Tetra- (4)
- Penta- (5)
Example Compounds
- As2S5 is named diarsenic pentasulfide.
- CO2 is correctly named carbon dioxide, not monocarbon dioxide.
- PCl5 is referred to as phosphorus pentachloride.
- SO2 is known as sulfur dioxide.
- P4S10 is called phosphorus decasulfide.
- CBr4 is identified as carbon tetrabromide.
- N2O4 is named dinitrogen tetroxide.
Characteristics of Binary Molecular Compounds
- Carbon is often a component of binary molecular compounds.
