Functional groups
In Topic S3.2, you learn about organic chemistry, which is the study of organic molecules. These are molecules that contain carbon and form living organisms, and you need to able to identify and name organic molecules.
This starts by classifying them into different groups based off unique atom combinations, called functional groups. There are eight key functional groups to learn:
- No functional group - classed as an alkane.
- Alkenyl group - classed as an alkene.
- Alkynyl group - classed as an alkyne.
- Hydroxyl group - classed as an alcohol.
- Carboxyl group - classed as a carboxylic acid.
- Carbonyl group - classed as an aldehyde or ketone.
- Ester group - classed as an ester.
- Ether group - classed as an ether.
There are four additional groups that may appear, but you do not need to know the class:
