Difference between aromatic compound and antiaromatic compound
Understand the Problem
The question is asking for the distinction between aromatic and antiaromatic compounds, which involves understanding their structural and electronic characteristics, stability, and the rules that govern their classification.
Answer
Aromatic compounds have 4n + 2 π electrons (stable), antiaromatic have 4n π electrons (unstable).
The main difference between aromatic and antiaromatic compounds is that aromatic compounds follow Hückel's rule, having 4n + 2 π electrons, while antiaromatic compounds have 4n π electrons. Aromatic compounds are cyclic, planar, and completely conjugated, making them stable, whereas antiaromatic compounds are unstable.

The main difference between aromatic and antiaromatic compounds is that aromatic compounds follow Hückel's rule, having 4n + 2 π electrons, while antiaromatic compounds have 4n π electrons. Aromatic compounds are cyclic, planar, and completely conjugated, making them stable, whereas antiaromatic compounds are unstable.
More Information
Aromatic compounds are characterized by their stability due to the delocalization of π electrons, making them less reactive. Antiaromatic compounds, on the other hand, are highly reactive due to their electron configuration. This fundamental difference in electron count and stability defines their chemical behavior and reactivity.
Tips
A common mistake is confusing the electron count for conjugated π systems. Ensure you differentiate between (4n + 2) π electrons for aromaticity and (4n) π electrons for antiaromaticity.
