Short Answer TypeExplain why an alkylamine is more basic than ammonia.
(a) The basicity of amines depends on the +I effect of the alkyl groups. With increase in alkyl group the +I effect will increase which will increase the ease of donation of lone pair electron. Amine will accept a proton and from cation will be stabilized in water by salvation (by hydrogen bonding).better the salvation by hydrogen bonding higher will be the basic strength.
Hence, alkyl amine is more basic than ammonia
CH3NH2 > NH3

Give reasons for the following:
i) Aniline does not undergo Friedal-Crafts reaction.
ii) (CH3)3N is more basic than (CH3)3N in an aqueous solution.
iii) Primary amines have higher boiling point than tertiary amines.
