Just ok

Geez

Not the information that was needed or expected by the title. There are all kinds of rules. Very dissappointed.

all i need to know about naming compounds

excellent, and i can rewind it 1000 times if i don't understand - awesome

Great!!

This is a great video, I used it to review for my final without having to reread most of the chapter. It's very clear and he uses good examples.

Below are the descriptions for each of the lessons included in the series:

• Chemistry: Describing Chemical Formulas

  In this lesson, you will learn the common nomenclature of chemistry. Professor Harman defines and contrasts atoms, molecules, ions, and ionic salts/covalent solids. Then Professor Harman covers written chemical formulas and visual representations of molecules. A molecular formula is a chemical formula that represents the actual number of atoms of each element within a molecule. An empirical formula is a chemical formula of a compound written with the smallest integer ratio of subscripts. Empirical formulas are always used to describe ionic compounds and covalent network solids. Various visual representations of molecules include the ball and stick three dimensional model that closely represents the structure of the molecule, a line drawing that approximates the structure in two dimensional terms, and a shorthand often used by organic chemists. Professor Harman warns that molecules are defined by their unique arrangements of atoms, and a formula can represent many different molecular compounds (known as isomers).

  Taught by Professor Harman, this lesson was selected from a broader, comprehensive course, Chemistry. This course and others are available from Thinkwell, Inc. The full course can be found at http://www.thinkwell.com/student/product/chemistry. The full course covers atoms, molecules and ions, stoichiometry, reactions in aqueous solutions, gases, thermochemistry, Modern Atomic Theory, electron configurations, periodicity, chemical bonding, molecular geometry, bonding theory, oxidation-reduction reactions, condensed phases, solution properties, kinetics, acids and bases, organic reactions, thermodynamics, nuclear chemistry, metals, nonmetals, biochemistry, organic chemistry, and more."

  Dean Harman is a professor of chemistry at the University of Virginia, where he has been honored with several teaching awards. He heads Harman Research Group, which specializes in the novel organic transformations made possible by electron-rich metal centers such as Os(II), RE(I), AND W(0). He holds a Ph.D. from Stanford University.

• Chemistry: Naming Chemical Compounds

  Naming chemical compounds can be tricky, and requires a little bit of knowledge about the trends and naming conventions. First, Professor Harman explains that how you name a compound will depend on the type of compound - whether it is an ion, molecular compound, acid, or base. For ions, the way you name the ion will depend on whether the compound is a cation or anion and whether or not it is monatomic, polyatomic, or a transition metal. Anions follow slightly more difficult naming conventions. Molecular compounds use Greek prefixes and will always start with the element furthest from Fluorine. Some molecular compounds have common names (such as water), and these are always used. Bases are simply named like ionic materials. Acids are named based on the suffix of the anion they are derived from. If the anion ends in -ate, the acid uses an -ic suffix. If the anion ends in -ite, the acid uses an -ous suffix.

• Chemistry: Organic Nomenclature

  As with previous chemical naming conventions, organic chemistry has its own nomenclature. Organic compounds are compounds with carbon. Hydrocarbons are compounds that contain only hydrogen and carbon in varying amounts. These are broken into three groups, alkanes, alkenes, and alkynes. Alkanes have an -ane suffix. Similarly, alkenes have an -ene suffix and alkynes keep the -yne suffix. Professor Harman teaches you the standard prefixes that are used to indicate the number of carbon atoms that are in each of the compounds. These include meth-, eth-, pro-, but-, and pent-. These prefixes also pertain to alcohols. Alcohols have an OH group connected to a hydrocarbon and can be identified by an -ol suffix. Once you know some of the common prefixes and suffixes, it is easy to identify characteristics of larger, unknown compounds.

  This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth!
