Classify the following amines as primary, secondary or tertiary:
(i)
(ii)
(iii) (C2H5)2CHNH2
(iv) (C2H5)2NH
(i) Primary. Because the nitrogen atom is attached to the only 1 carbon atom.
Note: The degree of amines depends on the no of atoms attached to the nitrogen atom of amine (except hydrogen).
(ii) Tertiary. Because the Nitrogen atom is attached to the 3 carbon atoms.
(iii) Primary. Because the nitrogen atom is attached to the only 1 carbon atom.
(iv) Secondary. Because the nitrogen atom is attached to the only 1 carbon.
