Short Answer TypeExplain how does the presence or absence of hydrogen on N of amines affect the modes of their reactions with nitrous acid?
If‘N’ is attached with 2 atoms of hydrogen, we get alcohol and nitrogen gas.
If ‘N’ is attached to 1 atom of hydrogen, we get the yellow oily compound , nitroso amines by replacing one H by NO.
If nitrogen is not attached with hydrogen, this protonation of tertiary amines will take place to form salt soluble in water.
Arrange the isomeric compounds:
(i) Ethyldimethyl amine
(ii) n-butyl amine
(iii) diethyl amine
in order of decreasing boiling point and give reason.
