Aromatics:
At the conclusion of our time
together, you should be able to:
1. Define an alkyl halide
2. Define an aromatic hydrocarbon
3. Explain the difference between cycloalkanes
and benzenes.
4. Name and write the formulas for alkyl halides,
cycloalkanes and benzenes.
Alkyl Halides
Organic compound with a halogen
General formula will have the halogen as
a side chain like:
•Fluoro
•Chloro
•Bromo
•Iodo
Naming Examples
2-flouro-3-methylpentane
CH3-CH-CH-CH2-CH3

F CH3
Naming Examples
1-chloro-4-methylpentane
CH3-CH2-CH-CH2-CH2

Bill Gates' Rules
Here is a list of 11 things that many high school
and college graduates did not learn in school. In
his book, Bill Gates talks about how feel-good,
politically-correct teachings created a full
generation of kids with no concept of reality and
how this concept has set them up for failure in
the real world.
RULE 10
Television is NOT real life. In real life people
actually have to leave the coffee shop and go to
jobs.
Cycloalkanes
Cycloalkanes are saturated
hydrocarbons in a ring structure.
They tend to have strong aromas.
Smaller ring structures have stressed
bonds that will require a spring, larger ring
structures will not have stressed bonds
and will not require a spring.
They are named with the prefix cyclo-.
Cycloalkanes
Cycloalkanes and Substituent Groups
The longest chain is named last. The
shorter chain is the alkyl group.

Type 2 Benzene
Benzene
The 3 double bonds rotate
rapidly (resonate) giving
benzene a great deal of
stability.
Benzene is the most
produced organic
compound.
What is the most produced
inorganic compound??
Sulfuric Acid!!
