Key Stage 4
Meaning
A functional group is a group of atoms responsible for the chemical properties of a compound.
About Functional Groups
There are four important functional groups you should know:
- Alkanes - The functional group is the single bonds between Carbon atoms and between Carbon and Hydrogen atoms.
- Alkenes - The functional group is the double bonds between Carbon atoms.
- Alcohols - The functional group is the OH group attached to a Carbon atom.
- Carboxylic Acids - The functional group is the double bond between a Carbon atom and an Oxygen atom and the single bond to an OH group on that same Carbon atom.
Examples
| Propane | Propene | Propanol | Propanoic Acid | |
| Chemical Formula | C3H8 | C3H6 | C3H8O | C3H6O2 |
| Structural Formula | CH3CH2CH3 | CH2CHCH3 | CH3CH2CH2OH | CH3CH2COOH |
