Amides, because of the hydrogen attached to the nitrogen atom, can form hydrogen bonds between themselves. They have higher boiling and melting points than corresponding alkanes. Since they can also form hydrogen bonds with water, amides containing up to five carbon atoms are soluble in water. Reactions of Amides. Amides are neutral in pH and undergo the hydrolysis reaction.
