Since the 1800s, our knowledge and understanding of chemistry has grown rapidly.  To make sense of all of this knowledge, chemists divided chemistry into three main categories: inorganic, organic and physical chemistry.  Each category is equally important.  There are millions of different compounds in existence, and the vast majority are organic compounds.  So..what is organic chemistry?  

This week you are going to investigate and find out. 

Are we ready?.....Get ready..... www.youtube.com/watch?v=FzyAjoBLzY8  and  www.youtube.com/watch?v=9iteRKvRKFA

LEARNING OBJECTIVES

Define the term “functional group” as it applies to organic molecules

KEY TAKEAWAYS

Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it would have in its original form.

  • Functional groups will undergo the same type of reactions regardless of the compound of which they are a part; however, the presence of certain functional groups within close proximity can limit reactivity.
  • Functional groups can be used to distinguish similar compounds from each other.

Key Terms

  • functional group: A specific grouping of elements that is characteristic of a class of compounds, and determines some properties and reactions of that class.
  • functionalization: Addition of specific functional groups to afford the compound new, desirable properties.

Task 1:  Use the videos and independent research to understand what functional groups are and how to name organic compounds.  Create a spider diagram and a set of rules for naming alkanes and alcohols.  

Task 2:  make models using whatever you can - be creative - of ethanol and ethoxyethane. 


You are now going to look at what isomerism is and what the difference is between structural and stereo - isomerism. 

Task 3:  Answer the two questions below. 

Draw a structure for each of five isomers with the molecular formula C6H14.

There are three ways to attach two CH3 groups and two Cl atoms to C=C.  Draw these structures and use your knowledge of nomenclature and cis-trans isomerism to name them.
