Hydrocarbons
Contain Only Carbon and Hydrogen |
| 12.1a |
About Organic Chemistry |
Summary:
Organic chemistry is the study of carbon-containing compounds.
Organic compounds can occur naturally or be created synthetically.
This video lesson explains why the carbon atom is so special.

Hydrocarbons |
Summary:
A hydrocarbon is an organic compound that contains only hydrogen
and carbon. This video lesson introduces three ways to depict
organic molecular structures. Structural isomers are also defined.

Conformation and Configuration |
Summary:
Configuration is how atoms are connected. Conformation is the
spatial orientation of a particular configuration. |

Where
Do Hydrocarbons Come From? |
Summary:
The main source of hydrocarbons is from fossil fuels, especially
crude oil. How crude oil is transformed into various hydrocarbons
is discussed. |

Unsaturated Hydrocarbons Contain Multiple Bonds |
| 12.2a |
Saturated
and Unsaturated |
Summary:
There are two classes of hydrocarbons: saturated and unsaturated.
In a saturated hydrocarbon, each carbon atom is bonded to four
atoms. In an unsaturated hydrocarbon, there is one or more double
or triple bonds. A special case of an unsaturated hydrocarbon
is benzene. |

Organic
Molecules Are Classified by Functional Group |
| 12.3a
|
Functional
Groups |
Summary:
Organic molecules are classified by the functional groups they
contain. Most functional groups contain a heteroatom, which
is any atom other than hydrogen or carbon in an organic molecule.

Alcohols
Have a Hydroxyl Group |
Summary:
Alcohols contain the hydroxyl functional group. A hydroxyl group
is a hydrogen and an oxygen connected to a carbon atom. This
video lesson includes a dramatic demonstration of the combustion
of an alcohol. |

Phenols,
Ethers, and Amines |
Summary:
The phenol group consists of an aromatic ring and a hydroxyl
group. Phenols are acidic and antiseptic. Ethers contain an
oxygen bonded to two carbons and some ethers are anesthetic.
Amines, based on the amine functional group, form alkaline solutions.

Compounds
With a Carbonyl |
Summary:
A variety of functional groups contain what is known as a carbonyl,
which is a carbon atom double bonded to an oxygen atom. This
includes the ketone, aldehydes, amides, carboxylic acids, and
esters. |

Organic
Molecules Can Link To Form Polymers |
| 12.4a
|
Addition
Polymers |
Summary:
Organic polymers are defined and then a special class of polymers,
the addition polymers, are described. |
Duration:
4:55. |
| 12.4b
|
Condensation
Polymers |
Summary:
Condensation polymers are made from organic molecules that have
two reactive functional groups on opposites sides of the molecule.
The synthesis of nylon is demonstrated. |

Kai and
Maile: Racing Water Drops |
Summary:
Kai and Maile explore the effects different plastics have on
drops of water. BTW, “a hui hou” is the Hawaiian phrase
for: “until next time.” |
