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.
