It has a functional group of NH2.
1. They can dissolve in water.
2. They are gases and liquid.
3. They have fishy odour.
1. As bases they neutralize acids.
2. They dissociate/ionize in water e.g. CH3NH2 + H2O CH3NH3++ OH–
1. Used in making nylon
2. They can also be used in making polyamide.
1. State two (2) physical properties and two (2) chemical properties of amine.
2. Give the classes of amine according to the number of their alkyl groups.
It has functional group of –C which is known as carbonamide group.
1. Only methanamide is a liquid while others are solid.
2. They have high melting point and high boiling point.
1. Amide can be hydrolysed in the presence of alkali and mineral acid e.g.
CH3CONH2 + H2O → CH3COOH + NH3
2. In the presence of sodium hydroxide and bromine, amides produce amines with elimination of one carbonyl group.
e.g.CH3CONH2 + Br2 + 4NaOH → CH3NH2 + 2NaBr + Na2CO3 + 2H2O
1. Used in the preparation of amines.
2. Used in making synthetic resins and plastics.
3. It can also be used in making fertilizer.
This is an amide of hydrogen trioxo carbonate (IV) acid. It is produced by compressing CO2 and NH3 at high pressure at 2000C.
1. Write the structural formula of amide.
2. Give one different between amine and amide.
