What does the term "functional group" mean in reference to the structure of organic molecules? Identify two types of
functional groups and describe their chemical properties. What will be an ideal response?
ANSWER: A functional group is a group of atoms that is attached to the carbon skeleton and determines
the types of chemical reactions and other associations in which the resulting organic
molecule participates. Table3-1 shows the main functional groups and their properties.
