Pyridine (C5H5N) and pyrazine(C4H4N2) have structures similarto benzene. Both compounds have structures with 6 atoms in aring. Draw Lewis structures for pyridine and pyrazine showingall resonance forms. the N atoms in pyrazine are directlyopposite each other in the ring with 2 carbons between them ineither direction. Indicate resonance with a double-headedarrow between structures. Draw the Lewis structures with theformal charges minimized.
