MCQ
  • Piperidine $>$ Pyridine $>$ Pyrrole
  • B
    Pyrrole $>$ Pyridine $>$ Piperidine
  • C
    Pyridine $>$ Piperidine $>$ Pyrrole
  • D
    Pyrrole $>$ Piperidine $>$ Pyridine

Answer

Correct option: A.
Piperidine $>$ Pyridine $>$ Pyrrole
a
Order of basic strength is

$\mathrm{N}\left(\mathrm{sp}^3\right.$, localized lone pair $)>\mathrm{N}\left(\mathrm{sp}^2\right.$, localized lone

pair $)>\mathrm{N}\left(\mathrm{sp}^2\right.$, delocalized lone pair, aromatic)

$\therefore$ Piperidine $>$ Pyridine $>$ Pyrrole
