Correct order of basic strength of Pyrrole, Pyridine and Piperidine is:

(A)Piperidine $>$ Pyridine $>$ Pyrrole✓ Correct
(B)Pyrrole > Pyridine > Piperidine
(C)Pyridine > Piperidine > Pyrrole
(D)Pyrrole > Piperidine >Pyridine

Answer: (A)

Solution

Basicity depends on lone-pair availability: piperidine (sp³ N, localised lone pair) > pyridine (sp² N, localised) > pyrrole (lone pair delocalised into the aromatic ring). Option (1).
