Covalent Compounds form when two nonmetals and/or a metalloid and a nonmetal bond
To name covalent compounds
• Covalent compounds are composed of two or more nonmetals which share electrons. (Some metalloids are covalently bonded as well).
• USE PREFIXES mono = 1 penta = 5di = 2 hexa = 6tri = 3 hepta = 7tetra = 4 octa = 8
prefix of less electronegative atom (n ≠ 1), prefix of second atom– ending ide

• CO
• P2O5

Naming Organic Compounds
• Organic compounds have one or more carbons, surrounded with hydrogens.
• They may have double or triple bonds, and may include oxygen, or other atoms.
• They are named by counting the “carbon backbone” and applying a prefix
• “Functional Groups” provide the rest of the name.

Molecular and Empirical Formulas.• Molecular: adj. Pertaining to, consisting of,
caused by, or existing between molecules.
• Empirical: adj. 1. Relying upon or derived from observation or experiment. 2. Guided by practical experience and not theory, especially in medicine.
• Formula: n 1. an established form of words for use in a ceremony or procedure. 3. Chemistry: a. a symbolic representation of the composition or of the composition and structure of a chemical compound. b. The chemical compound so represented. c. A prescription in exact proportion: recipe.
