Naming and Properties of Amides
- The amide functional group has a carbonyl group (-C=O) bound to a N atom
Properties:
- Have the polar carbonyl group and primary and secondary amides also have N-H bonds giving them the ability to hydrogen bond with themselves
- More N-H bonds means that amide will have a higher boiling point (more hydrogen bonds)
- Boiling points are higher than other hydrocarbon derivatives of the same size
Naming:
Example: Name the following molecule
methanamide
Example: Name the following molecule
N-ethyl-N-methyl-2-methylbutanamide
Forming Amides
Name the amide in the reaction above:
N-methylpropanamide
The first part of the name comes from the amine
The second part of the name comes from the carboxylic acid
