Define Aromaticity . ?

Aromatic compounds are substances that consist of one or more rings that contain alternating single and double bonds in its chemical structure. In real life, many aromatic compounds have an odor, however, there are some compounds that are chemically aromatic, but do not have a distinct smell.

For example, benzene is an aromatic compound. 

The term 'aromatic' is used by chemists for substances with distinct odors. In this lesson, we will learn all about aromatic compounds, the features of such compounds' chemical structures, and Huckel's Rule.

What Are Aromatic Compounds

Take a moment and think of substances that have a strong fragrance. What kind of things come to your mind? Perfume, vanilla or, perhaps, even cinnamon? All of these are fragrant or aromatic. While they certainly smell differently, they do have something in common: these substances are made of aromatic compounds.
