CHEM103: Organic Chemistry I

Unit 2: Overview of Organic Chemistry: Functional Groups and Classes of Chemical Reactions   Here you will learn the basic concepts necessary to understanding the rest of the course.  Each of these concepts will be mastered in the appropriate units ahead, but a general overview is necessary at this point. 

In this unit, you will learn how to classify organic molecules based on their functional group(s).  A functional group is a group of atoms that presents characteristic physical and chemical properties, such as chemical reactivity or spectroscopy behavior.  You will also learn how to use arrow notation to indicate movements of electrons in organic reactions.  The unit will conclude with an introduction to organic reactions and an explanation of how to classify a reaction based on a particular technique or reagent.

Unit 2 Time Advisory
This unit will take approximately 15 hours to complete.

☐    Subunit 2.1: 5 hours

Unit2 Learning Outcomes
Upon successful completion of this unit, the student will be able to:

  • Identify various organic functional groups and assign a particular molecule to the family of organic compound to which it belongs.
  • Use curve arrow notation to show movements of electrons.
  • Describe—in general terms—organic reactions.
  • Give the definition of “basicity,” "nucleophile," and "electrophile."
