Organic Chemistry----Nomenclature

CH4

• organic chemistry is the study of carbon compounds(carbon forms multiple covalent bonds)
• carbon compounds can form chains, rings or branches
• simplest organic compounds are made of carbon and hydrogen
• saturated compounds have no double or  triple bonds
• compounds with only a single bonds are called Alkanes and always end in -ane

Nomenclature

There are 3 types of Organic compounds:

1. straight chains
2. cyclic chains
3. aromatics

Straight chain rules

1. Circle the largest continuous chain and name them as the base chain (ex. meth, eth, prop)
2. Number the base chain so side chains have the lowest possible numbers
3. Name each side chain using the -yl ending
4. Give each side chain the appropriate number (if there is more than one identical side chain numbers, labels are slightly different)
5. List side chains alphabetically

EX.

             

3-ethyl 2,4 dimethyl pentane
