Concept explainers
(a)
Interpretation:
The increasing order of basicity of the given compounds is to be stated.
Concept Introduction:
Pyridine is a heterocyclic compound which contain nitrogen atom as heteroatom. The lone pair of nitrogen atom pyridine is not delocalized over the ring. Pyridine is basic in nature. The basicity of pyridine compounds changes with substitution. Basicity of pyridine compounds depends on the nucleophilicity of their nitrogen lone pair.
(b)
Interpretation:
The increasing order of basicity of the given compounds is to be stated.

(c)
Interpretation:
The increasing order of basicity of the given compounds is to be stated.
Concept Introduction:
The basicity of compounds can be compared by comparing the stability of their conjugate acid. If the conjugate acid formed is more stable than the basicity of compound will be greater. Resonance structure containing positive charge on electronegative atom is less stable.
(d)
Interpretation:
The increasing order of basicity of the given compounds is to be stated.
