To find: Identify the stronger base in the given pair of compounds (a)
Find the behavior of nitrogen atom in pyridine
(b)
Interpretation: The stronger base has to be identified in the given pair of compounds
Concept Introduction:
If the lone pair of electrons on nitrogen atom in amine compound is delocalized, that compound is resonance stabilized. It is also involved in aromatic stabilization. As a result, a number of resonance structures are drawn for the delocalization of electrons in the structures. So, the compound has less basic character. If the lone pair of electrons on nitrogen atom in amine compound is localized, that compound doesn’t involve in resonance stabilization. So, that compound has more basic character. sp3 hybridized nitrogen atom is expected to function as more basic character than sp2 hybridized nitrogen atom which has again basic character than sp hybridized nitrogen atom.
