Practice Problem: Aromaticity

The video tutorial explains aromaticity, focusing on the criteria for a molecule to be aromatic: it must be planar, fully conjugated, and satisfy Huckel's rule. The instructor analyzes several molecules, identifying which are aromatic, non-aromatic, or anti-aromatic. Special attention is given to heterocycles, where lone pairs may or may not participate in conjugation to achieve aromaticity.
