Functional Groups Flashcards
1- Introduction to Organic Compounds and Functional Groups
an atom or a group of atoms with characteristic chemical and physical properties
Functional Groups
What constitutes a functional group?
It contains a heteroatom, a multiple bond, or SOMETIMES both.
3 Types of Functional Groups
- Hydrocarbons
- Compounds with a Single Bond to a Heteroatom
- Compounds with a C=O Group (Carbonyl Group)
organic compound composed ONLY of hydrogen and carbon atoms;
simplest type of organic compound
Hydrocarbon
two main classes of Hydrocarbons
aliphatic and aromatic
hydrocarbons that do NOT contain the benzene group, or the benzene ring
Aliphatic Hydrocarbons
hydrocarbons that contain one or more benzene rings
Aromatic Hydrocarbons
a six-membered ring with three double bonds
Benzene Ring
three main subcategories within aliphatic hydrocarbons
- Alkanes
- Alkenes
- Alkynes
- have ONLY C-C single bonds and NO functional group
- often described as saturated
Alkanes
- have a C-C double bond as their functional group
- also called olefins
Alkenes
have a C-C triple bond as their functional group
Alkynes
general formula of alkanes
