With the large growth of carbon compounds, it was necessary to name these compounds in a more systematic way.
The suffix denotes the type of bonds or the functional group present in the carbon chain, e.g.
| Type of bond | Functional group |
| ane (single bond) | ol for alcohols (-OH) |
| ene (double bond) | al for aldehydes (-CHO) |
| yne (triple bond) | oic acid for carboxylic acid (-COOH) |
This denotes the presence of other functional groups and their position.
For e.g., the following compound can be named as:
