A functional group can be thought of as a modification to an alkane carbon chain or ring and is identified by pi bonds or elements different from carbon or hydrogen. 

Nomenclature of Functional Groups

Concept #1: Identifying and Naming Functional Groups

Based on the functional group present the end of the alkane name can change. 

Example #1: Provide the name of the following alcohols and alkyl halides and state if they are primary, secondary or tertiary. 

Example #2: Provide the name of the following functionalized organic compounds. 

Example #3: Provide the name of the following functionalized organic compound. 

Example #4: Provide the name of the following amines and state if they are primary, secondary or tertiary. 

Example #5: Provide the name of the following ethers.

Example #6: Provide the structure of the following aromatic hydrocarbons.

p-ethyltoluene

Example #7: Provide the structure of the following aromatic hydrocarbons.

m-bromobenzoic acid

Example #8: Provide the structure of the following aromatic hydrocarbons.

2,4,6-trimethylnitrobenzene
