Hydrogen Bonding and Carbonyls
Carbonyl compounds can form hydrogen bonds with water, and this affects their properties.

Pure carbonyls
- Pure carbonyl compounds do not hydrogen bond to each other.
- This is because a hydrogen bond requires a hydrogen connected to a highly electronegative element like oxygen or nitrogen.
- Carbonyl compounds do not have these hydrogens.
- This means they have a low boiling point and are quite volatile.
In water
- Carbonyl compounds dissolve in water because they can form hydrogen bonds with water.
- The oxygen of the carbonyl is attracted to the hydrogens of the water molecules.
- This means carbonyl compounds are highly soluble in water.
