Question

Complete the Lewis structures for pyridine (C5H5N) showing the two most common resonance forms. Draw the Lewis structures with the formal charges minimized.

Answer 1

In the picture attached, the Lewis structures for pyridine (C5H5N) are shown .

Step-by-step explanation:

To draw this Lewis structure take into account that pyridine is a cyclic compound and it is structurally related to benzene, with one methine group replaced by a nitrogen atom (notice that with nitrogen, 2 electrons are not included in the bonds with carbon atoms). Resonance structures are drawn by analogy with benzene's resonance structures.

Answer 2

Look at the picture.

Step-by-step explanation:

So on picture two resonance structures are shown. You can see that nitrogen's electron pair is not used in aromatic system and is planar to the ring.
