Explain how does the presence or absence of hydrogen on N of amines affect the modes of their reactions with nitrous acid?
Arrange the isomeric compounds:
(i) Ethyldimethyl amine
(ii) n-butyl amine
(iii) diethyl amine
in order of decreasing boiling point and give reason.
Explain the following general order of basicity in aqueous solution:
R2NH > RNH2 > R3N > NH3
Explain the following general order of basicity in aqueous solution:
R3N ,R2NH , RNH2
What will be the basic strength order of these amines in gas phase?
In the gas phase there is no solvation effect, only the number of R's and their inductive effect determines the basicity.
More the number of R's, more the basicity. The basicity order will be their,
R3N > R2NH > RNH2
