(b)
Interpretation:
The structural effects in the given amines with their basicities are to be stated.
Concept introduction:
Basicity of amines depends upon the nature of substituent present on the aromatic ring. If substituent is electron withdrawing group then it has tendency to decrease the electron density and thus results in decrease in basicity of amines, whereas electron donating groups enhance the electron density and increases the basicity.
(c)
Interpretation:
The reason as to why the given compound is not only a stronger base but also a stronger hydroxide ion is to be explained.
