ifunctional groups and homologous series are very confusing ......i just want to understand it better please help me..
A series of organic compounds that have similar structural features but differ from adjacent members by (-CH2) group is referred to as homologous series. Each member of homologous series is called homolog.
1. CH3-OH, CH3-CH2-OH, C3H7-OH are the members of a homologous series called "Alcohols".
2. CH3-COOH, CH3-CH2-COOH, C3H7-COOH are the members of homologous series called "Carboxylic acids".
3. CH3-O-CH3, C2H5-O-CH3, C3H7-O-CH3 are the members of homologous series called "Ethers".
Functional Groups : There are certain atoms or groups of atoms known as functional groups which gives the compounds their characteristic properties.
|F, Cl, Br, or I||Alkyl halide||CH3Br (methyl bromide)|
|Ether||CH3OCH3 (dimethyl ether)|
|Amine||CH3NH2 (methyl amine)|
