1. Naming and Drawing Carbon Compounds
Today you will learn:
How to name a simple hydrocarbon when given its formula.
Draw the structural formula when given the name.

2. I. Naming Straight Chained Hydrocarbons
Inorganic carbon compounds, such as CO2, are named using the system with prefixes and suffixes.
Most organic compounds are found in living things.

3. Naming Hydrocarbons
Alkanes end with the suffix –ane.
Ex: Methane CH4

4. Naming Hydrocarbons 1 C = Meth-ane 2 C = Eth-ane 3 C = Prop-ane
4 C = But-ane
5 C = Pent-ane Notice that #5-10
6 C = Hex-ane Use the latin prefixes.
7 C = Hept-ane
8 C = Oct-ane
9 C = Non-ane
10 C = Dec-ane

5. Alkenes & Alkynes
C. The names of alkenes and alkynes use the same prefixes as the alkanes but with a change in the suffix to identify that double or triple bonds exist in the molecule.

6. Unsaturated Hydrocarbons
Unsaturated hydrocarbons with double bonds (alkenes) or triple bonds (alkynes).
1. The names of alkenes end with –ene.
Ex: C2H4, ethene

7. Unsaturated Hydrocarbons
The names of alkynes end with –yne.
Ex: C2H2, Ethyne

8. Determining Position of Double/Triple Bond
The number of the carbons in the molecule is what determines the name of the whole chain.
The number out in front is where the multiple bond is located.

9. Multiple Multiple Bonds
F. If there is more than one multiple bond in the molecule the prefixes di- , tri-, etc. are used to denote the number of multiple bonds.

10. Branching
The branch number is the carbon of the main chain the branch is coming off then we name the carbons in the branch the prefix of a normal chain.

11. Saturated Fats & Unsaturated Fats
Saturated fats are made of long straight chains of single-bonded carbon and hydrogen with a carboxyl acid group on the end.
Unsaturated Fats contains one or more double bonds.

12. II. Drawing Organic Molecules
There are four ways to represent an organic molecule:
Chemical Formula C6H12
Structural Formula
Skeletal Structure
Space filling model

13. Skeletal Structures
The skeletal structures leave out some or all of the carbon and hydrogen atoms.
1. Shows the framework only as lines representing bonds and angles or an end points representing the carbon atoms.
2. It simplifies complex carbon molecules.
