Organic Compounds
• Also known as Hydrocarbons
• Organic compounds contain C, H, and
usually O
Hydr o carbon
Hydrogen
Oxygen
Carbon
Structure
• Organic compounds are formed of carbon
chains called carbon backbones
• A carbon chain is two or more carbons
linked together in a row
Drawing
• To draw an organic molecule write # of
carbons in a straight line and connect
them with single bonds
• Next give carbon four bonds
• Each bond that you added to carbon put a
hydrogen on that bond

Naming
•
We name organic compounds by adding
prefixes (according to the # of C’s) to
base names

Alkane
• The simplest group is the alkane group
• Alkane is an organic compound with only
single bonds
• The base name for Alkane is -ane
• To name Alkanes add prefix to -ane
