Question

Pyridine is less basic than triethylamine because .
A. pyridine has aromatic character
B. nitrogen in pyridine is `sp^(2)`-hybridized
C. pyridine is a cyclic system
D. in pyridine the lone pair of nitrogen is delocalized .

Answer 1

Correct Answer - B
In both these compounds the lone pair of electrons on `N` is not delocalized throught resonance But pyridine is less basic because the lone pair of electrons on `N` atom is in `sp^(2)` hybrid orbital and hence more trightly bound to the nucleus
