Interpretation Introduction
Interpretation:
The contributing structures for pyridine have to be drawn.
Concept Introduction:
Contributing structures:
The double bonds of an aromatic compound shift back and forth very rapidly which is known as delocalization. The resulted forms or structures cannot be separated and stay in equilibrium with charge separation. Those structures are known as contributing structuresof that compound.
