Organic Chemistry


Organic Chemistry is the study of carbon compounds. Carbon can form multiple covalent bonds such as chains, rings, or bracelets. There are less than 100,000 non-organic compounds while, organic compounds number more than 17,000,000. The simplest organic compounds are made of carbon and hydrogen.
Ex.
CHCCH3
CH3CH3

CH4









Saturated compounds have no double or triple bonds. Compounds with only single bonds are called Alkanes and always end in -ane.

Nomenclature (naming)
There are 3 forms of bonds in Organic Chemistry:
Straight chains, Cyclic chains, and Aromatics

1) Straight chains
To name Straight chains:

  • Circle the longest continuous chain and name this as the base chain.

The base chain can either be the red or green from the drawing above because both chains are in equal length.

  • Number the base chain so side chains can have the lowest possible numbers



  • Name each side chain using the suffix -yl
"Meth" has 1 so theres a methyl, and "eth" has 2  so it's ethyl

  • Give each side chain the "appropriate number" ( if there is more than 1 identical side chain numbers/labels are slightly different: 2 methyl 4 ethyl
  • List side chains alphabetically
So the Name for this structure is 4 ethyl 2 methyl hexane
