Heterocycles Part 2: Pyridine

The video tutorial explores pyridine, a six-membered heteroaromatic compound similar to benzene but with a nitrogen atom. It discusses pyridine's aromaticity, basicity, and chemical reactions, including nucleophilic and electrophilic substitutions. The tutorial also covers pyridine synthesis, its derivatives, and the biological significance of heterocycles in natural products like DNA and vitamin B6.

What are the stable derivatives of pyridine that contain two nitrogen atoms?

How do the reactivities of pyridine derivatives compare to that of pyridine itself?

Identify some natural products that contain nitrogenous bases similar to pyridine.
