HALIDES: in this functional group halogen atoms replace a hydrogen atom. the
prefixes are: bromo, chloro, and floro

Ex: 3,2 dibromo 3 chloro 1 propane

ALCOHOLS: add 'OH' and change the ending to 'ol'

Ex: 3 ethyl 4 propyl 1 octanol

KETONES: there is an oxygen atom double bonded
to carbon. the ending is 'one'

Ex: 2 chloro 4 methyl 3 hexanone

ETHERS: an oxygen atom joins carbon chains together.
the ending is 'yl'

Ex: diethyl ether

05/06/10 - DAY 1D

This class we had a substitute. Mr. Doktor and half of the class went to Physics Day at Playland. We just had free time and we watched Mythbusters for the whole class and worked on our Organic Worksheets Mr. Doktor had given us the class before.

Organic Chemistry

There are more carbon compounds than all ionic compounds combined.
The study of carbon compounds is called organic chemistry.
Carbon can have multiple bonds and form many different shapes.

Hydrocarbons

Aliphatics
Alkanes
Alkenes
Alkynes
Alicyclics
Aromatics

Hydrocrabons have 3 types of formulas: Molecular Formula, Condensed Structural Formula, Structural Formula

Isomers are compounds that can be drawn in more than 1 way

NAMING ALKANES

1. Name the longest chain by using the correct suffix and adding "-ane"

2. Locate any branches by numbering carbon atoms

(use the lowest possible number system)

3. Name branches by using appropriate suffix and "-yl" ending (Alkyl branches)

4. If there are more than one of the same alkyl group, number each one and add the multiplier number in front of the branch name

ALKENES

Compounds w/ double bonds and end in "-ene"
Put a # in front of the parent chain that indicates where the double bond is
More than 2 double bond changes the parent chain slightly

ALKYNES

For compounds w/triple bonds use "-yne" endings
Follow all the same alkene rules

5:15 PM

05/10/10
Cyclo Alkanes:
- follow the same naming rules and add 'cyclo' in front of the parent name.
-if a cyclic chain is a side chain use 'cyclo____yl'
-resonance structure= 6 carbon cyclic chain called benzene
