| 1. | Pyridine was discovered in 1849 by the Scottish chemist bone oil.
|
| 2. | The chemical structure of pyridine was determined decades after its discovery.
|
| 3. | Pyridine is readily degraded by bacteria to ammonia and carbon dioxide.
|
| 4. | The reaction is catalysed with weak base like piperidine or pyridine.
|
| 5. | The balanced chemical equation, using methanol and pyridine, is:
|
| 6. | Pyridine is nitrated to 3-nitropyridine and 4-nitropyridine.
|
| 7. | Included are pyridine, thiophene, pyrrole, and furan.
|
| 8. | Electron lone pair availability ( basicity ) is decreased compared to pyridine.
|
| 9. | Pyridine is conventionally detected by the gas chromatography and mass spectrometry methods.
|
| 10. | The nitrogen center of pyridine features a basic lone pair of electrons.
