Summary

• Organic chemistry is the study of carbon
  compounds
• Carbon-
• differentiates living from nonliving matter
• shares its four valence electrons
• bonds to form organic molecules skeletons.
• Hydrocarbons form when hydrogen bonds with the
  skeleton.
• Isomers-
• Structural isomers differ in their double
  covalent bonds location
• Geometric isomers have different spatial
  arrangements
• Enantiomers mirror each other

Clarification

• Vitalism-
• life cannot be created with science
• Isomers-
• Aka congruent , basically theyre similar
• Structural Isomers-
• Same compounds, different shapes.
• Geometrical Isomers-
• Similar shape, different arrangements.
• Enantiomers-
• Two compounds copying one another, but flipped

Questions

• Define organic Chemistry.
• Evaluate the role of hydrocarbons in lipids.
• Why is carbon referred to as the backbone of
  biological molecules?
• What are the three types of isomers? Explain the
  significance.
• How is Carbon so versatile?

7
Prediction

• In Chapter 4, compounds that contain carbon are
  organic.
• In Chapter 8, we'll be learning about the carbon
  cycle.
• We learned about organisms as sources of valued
  substance. We will learn about organism's
  schedule of reproduction and survival in Chapter
  52.

The End

• Have fun exploring
