Pyridine - Wikipedia
网页Pyridine is a basic heterocyclic organic compound with the chemical formula C 5 H 5 N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom (=N−). It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell.

网页Pyridine. Pyridine is an example of a six-membered aromatic heterocycle. In the bonding picture for pyridine, the nitrogen is sp2-hybridized, with two of the three sp2 orbitals forming sigma overlaps with the sp2 orbitals of neighboring carbon atoms, and the third nitrogen sp2 orbital containing the lone pair.

网页2024年4月22日 · What are pyridines? Pyridine is a colorless liquid that boils at 115 ºC. It used to be obtained almost exclusively from coal tar. Today, it is obtained industrially from ammonia and acetylene. Pyridine like benzene has 6 π electrons (aromatic Hückel). Its structure is planar with bond angles of 120º.
