• Organic chemistry is the study of compounds
that contain CARBON.
• Almost all carbon-containing compounds are
organic (both natural and synthetic)
• Inorganic compounds generally DO NOT
contain carbon
Exceptions: CO, CO2, ionic carbonates (-CO3)
are all inorganic
• Carbon is very versatile due to its 4 valence electrons.
(allows for 4 bonds)
C

4H
H
H C H
H
• Carbon is usually bonded to H, O or other non-metals
• Carbon can bond with itself to form long chains of
carbon atoms (polymers; eg: petroleum & plastics)
• Organic compounds always have C before H in their
formulas (eg: CH4)
Hydrocarbons
• Contain only C and H atoms
polyethylene
•
•
C5000H10000
(plastic)
Hydrocarbons are flammable and many are used as fuels
See table 5.8 (page 247 in textbook) or page 96 in workbook
Alcohols
• Contain C, H and O atoms
•
All alcohols are poisonous and flammable
