please explain aromaticity in a nutshell, it looks interesting
Both Google and Wikipedia are your friends ...

In organic chemistry, the term aromaticity is used to describe a cyclic (ring-shaped), planar (flat) molecule that exhibits unusual stability as compared to other geometric or connective arrangements of the same set of atoms. As a result of their stability, it is very difficult to cause aromatic molecules to break apart and to react with other substances. Organic compounds that are not aromatic are classified as aliphatic compounds -- they might be cyclic, but only aromatic rings have especial stability (low reactivity).
