Organic Compounds

7th Grade Pre-AP presentation

1. The Amazing World of Organic
Compounds!

2. Time to “Test” last year’s knowledge
Create a KWL Chart
What do you know?
What would you like to know?
What did you learn?

4. •Identify that Organic
compounds contain Carbon
•Distinguish between Organic
and Inorganic Molecules
•Analyze various compounds
present in living organisms

7. An organic compound always includes carbon
joined to either itself or hydrogen.

8. When two or more elements combine together it is
called a compound.
Compounds can be classified into two main groups:
inorganic and organic.
Inorganic
Organic
Carbon Oxygen

9. The Importance of Carbon
…but not every compound containing
carbon is organic.
All organic compounds contain carbon...

Other Elements in Organic Compounds
oxygen
Other elements can be in organic compounds such as:
nitrogensulfur
Carbon and hydrogen are not the only elements that
might be in organic compounds.

11. Importance of Carbon
•Carbon has the
ability to join
with several
chemicals at the
same time.
•It can also join
with itself easily.
•Carbon
comprises about
19% of the
weight of an
animal and about
12% of the
weight of a
plant.

Nonmetal
Carbon
Hydrogen
Oxygen
Nitrogen
Phosphorus
Sulfur
All these elements could be present in Organic Compounds!

13. Lets classify different compounds!
What are your 4 classifications?
Which compound did you place under each category?
Why did you place them under that category?

14. What do you know about the word MONO
What do you know about the word POLY
Mono-mers and Poly-mers
A molecule that may react chemically to another molecule of the
same type to form a larger molecule.
Then what’s a Polymer?
Made from monomers linked by chemical bonds and make a
compound.

15. Lets use our compounds to differentiate between
Monomers and Polymers
Which you think is the Polymer?
