Question- pyridine and pyrazine have structures similar to, Ask an Expert

Academics

Question- Pyridine and pyrazine have structures similar to benzene. Both compounds have structures with six atoms in a ring. Draw Lewis structures for pyridine and pyrazine showing all resonance forms. The N atoms in the pyridine are opposite each other in the ring with 2 carbons between them in either direction. Indicate resonance with a double headed arrow between the structures. Draw the Lewis structures with the formal charges minimized.
