1. The Chemistry of Carbon
Do Now: Please Copy (Ignore what is on
handout):
Quiz Thursday 10/6
Topics:
Special Properties of Water
Polarity & Hydrogen Bonding in Water
Solutions
pH and buffers

2. Carbon
• What is it?
• Where do we find it?
• Why is it so important?
• How is it unique?

3. Carbon:
Element of Life
• Plants and other
autotrophs build
their own carbon-
based food out of
CO2 in the air.
• Animals and other
heterotrophs break
down carbon-based
food for energy

4. Carbon is Important!
• Natural Gas, Gasoline, Crude Oil, and
other fuels are all carbon compounds
• All plastics
• The molecules organisms are made of,
like sugars, fats, proteins, and even DNA.
• Too many to list!!!

5. Carbon forms many types of bonds
• Carbon has 4
valence
electrons, so
it usually
makes 4
covalent
bonds.
• Most atoms
make less
(O-2, H-1, N-
3)
•Organic Compound: a
compound that contains 2
or more carbon atoms.

6. Carbon can form different
structures…
• Chains
• Branched
Chains
• Rings

7. …and form single, double, & even
triple bonds.

8. Functional Groups give carbon
molecules even more diversity.
•A functional group is a
group of atoms that give the
molecule they are a part of
certain chemical
characteristics.

9. Carbon Polymers – Essential to Life!
• MONOMER
• POLYMER

10. In Summary…
• Organic compounds contain more than 1
carbon atom
• Carbon is REQUIRED by ALL living things –
other than water, it is in almost every other
chemical your body is made of.
• Because carbon can make 4 covalent bonds,
and bond with many other elements, carbon
can make many different types of chemicals.
• Many organic compounds are polymers: long
chains of repeating subunits

11. Read all about it! (Homework)
• Read pp. 52-54
• NOT last section “Energy Currency”
• Answer 1-3

12. Life in Deep Space?
• The article you have discusses recent
discoveries of carbon compounds in
space.
• Read the article on your own
• 4 roles to play in each group: Questioner,
Passage Master, Word Wizard, or Artful
Artist

13. Polymer Formation and Break-down
