Pyridine is less basic than triethylamine because .

Options

A. Pyridine has aromatic character
B. Nitrogen in pyridine is `sp^2` hybridized
C. Pyridine is a cyclic system
D. In pyridine, lone pair of nitrogen is delocalized

Answer

D

Explanation

Basicity of amines is due to availability of an unshared pair (lone pair) of electrons on nitrogen . This lone pair of electrons is available for the formation of a new bond with a proton or Lewis acid .
Pyridine is less basic than triethylamine because lone pair of electron in nitrogen in pyridine is delocalised.
