Answer
An atom, radical or bond which defines the structure of an organic compound and confers characteristic properties to it is known as a functional group.
| Group | Name | Example |
|---|---|---|
| C=C | carbon-carbon double bond | Ethene (C2H4) |
| -C≡C- | carbon-carbon triple bond | Ethyne (C2H2) |
| -OH | Hydroxyl | Methanol (CH3OH) |
| -CHO | Aldehydic | Methanal (HCHO) |
| -COOH | Carboxylic | Methanoic acid (HCOOH) |
| X = -F, -Cl, -Br, -I | Halo | Chloro Methane (CH3Cl) |
| -C=O | Ketonic | Propanone (CH3-CO-CH3) |
| -C-O-C- | Alkoxy | Methoxy Methane (CH3-O-CH3) |
