Organic Chemistry
Today we started a new unit: organic chemistry, this unit is mostly memorizing and has very little to do with equations themself
- There are more carbon compounds than all ionic compounds combined
- The study of carbon compounds is called organic chemsitry
- Carbon can have multiple bonds and form many different shapes





<-----table of what we will cover Hydrocarbons have three types of formulas:
















1) Molecular formulas

C3H8

2) Condensed Structural Formula
CH3-CH2-CH3

3) Structural Formula










Nomenclature of Hydrocarbons

- One molecular formula can have a number of different structures

- Isomers are compounds that can be drawn in more than one way

ALKANES

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

2) Locate any branches by number 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
