Organic Chemistry -- The chemistry of CARBON compounds.

Some of the examples in our everyday life:

clotting--polyester

plastic--polyethyiene

Organic Compounds properties:

1. low melting points

2. weak or non-electrolytes

3. can form chains of CARBON atoms that are linked in a

STRAIGHT LINE, CIRCULAR PATTERN and BRANCHED PATTERN.

Three types bonds:single bond, double bond, and triple bond.

Alkanes(unbranched)

1. Hydrocarbon compounds

2. Non-polar molecules

3. Tetrahedron Geometry

Naming Alkanes :ends with "-ane"

Examples:

Ethane

Names of Alkanes(needs to memorize!)

* An easy formula to memorize the above CNH2N+2

Branched Hydrocarbon

Hydrocarbons can have branched which are also hydrocarbon chains. They are also called subsitituted Hydrocarbon or Branched Hydrocarbons.

Alkyl group is an alkane which has lost one Hydrogen atom and replace by other alkyl group.

Example:

2,2,4-Trimethylpentane

If there have more than one of the same kind of Alkyl group, then use the prefix--"di", "tri"

Example:

Alkyl Groups

Methyl--CH3

Ethyl--CH2-CH3

Proply--CH2-CH2-CH3

Butyl--CH2-CH2-CH2-CH3

Pentyl--CH2-CH2-CH2-CH2-CH3

....

Last but not least, we have two videos that could help you get a better understanding of naming and drawing Alkane hydrocarbon .
