Covalent Compounds
Covalent compounds consist
predominately of covalent bonds.
The smaller the difference in electronegativity between
the elements the more covalent the compound.
Characteristics
1. Gases, liquids or solids with low melting
points
2. Many are insoluble in polar solvents (water)
3. Most are soluble in nonpolar solvents
(CCl4)
4. Molten compounds do not conduct electricity
5. Aqueous solutions are poor conductors of
electricity
6. Usually a NONMETAL and NONMETAL
Molecule - the simplest unit of a covalent
compound
Examples:
H2O H2 NH
3 CO2
