  • question_answer Pyridine is less basic than triethylamine because [AIIMS 2005]

    A) Pyridine has aromatic character

    B) Nitrogen in pyridine is \[s{{p}^{2}}\] hybridized

    C) Pyridine is a cyclic system

    D) In pyridine, lone pair of nitrogen is delocalized

    Correct Answer: D

    Solution :

               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.
