Study Notes

Naming Covalent Compounds

Compounds like P2O5 are named using prefixes to indicate the number of each type of atom. For P2O5, the name is diphosphorus pentoxide.
Prefixes for common elements are:
- mono- (1)
- di- (2)
- tri- (3)
- tetra- (4)
- penta- (5)
- hexa- (6)
- hepta- (7)
- octa- (8)
- nona- (9)
- deca- (10)

Examples of Compound Names

NCl3 is called nitrogen trichloride, with "tri-" indicating three chlorine atoms.
CBr4 is named carbon tetrabromide, using "tetra-" for the four bromine atoms.
As2O5 is referred to as diarsenic pentoxide, where "di-" and "penta-" denote two arsenic and five oxygen atoms, respectively.
N2O is dinitrogen monoxide; nitrogen needs no prefix as it is the first element.

Significant Examples and Reactions

N2O3 is called dinitrogen trioxide, indicating two nitrogen and three oxygen atoms.
The balanced reaction for the decomposition of nitrogen dioxide (2NO2) produces nitrogen and oxygen: 2NO2 → N2 + 2O2.
The incorrect name monocarbon monooxide fails to adhere to naming conventions; CO is simply called carbon monoxide.

Formulas of Common Compounds

The formula for phosphorus trihydride, or phosphine, is PH3.
NH3 is known as nitrogen trihydride, commonly called ammonia.
NO represents nitrogen monoxide, consisting of one nitrogen and one oxygen atom.

Compound Formula Notations

CO2 is carbon dioxide, with "di-" signifying two oxygen atoms.
P4S3 is tetraphosphorus trisulfide; "tetra-" indicates four phosphorus atoms and "tri-" shows three sulfur atoms.
B2Cl4 is named diboron tetrachloride due to having two boron atoms.

Specific Compound Examples

SiO2, known as silicon dioxide, consists of one silicon and two oxygen atoms.
B4H10 is tetraboron decahydride, indicating four boron and ten hydrogen atoms.
N2H4 is dinitrogen tetrahydride, commonly referred to as hydrazine.

Clarification on Misleading Names

Dihydrogen monoxide (H2O) highlights misleading information; it refers to water.
SO3 is sulfur trioxide, with "tri-" indicating three oxygen atoms.
ClO2 is appropriately named chlorine dioxide; incorrect naming may lead to mix-ups in element order and prefix use.

Advanced Compound Names

XeO3 is named xenon trioxide, where "tri-" represents three oxygen atoms.
P4S9 is tetraphosphorus nonasulfide indicating four phosphorus and nine sulfur atoms.
IF7 is iodine heptafluoride, employing "hepta-" to denote seven fluorine atoms.
