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

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
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.
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.

All these elements could be present in Organic Compounds!
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?
What do you know about the word MONOWhat do you know about the word POLY
Mono-mers and Poly-mersA 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.
Lets use our compounds to differentiate between Monomers and Polymers
Which you think is the Polymer?
