MCQ
Pyridine is less basic than triethylamine because
- APyridine has aromatic character
- BNitrogen in pyridine is $s{p^2}$ hybridized
- CPyridine is a cyclic system
- ✓In pyridine, lone pair of nitrogen is delocalized
✓
Answer
Correct option: D.
In pyridine, lone pair of nitrogen is delocalized
d
(d) 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.
(d) 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 nitrogen in pyridine is delocalised.
