Why aren't lower aromatic organic compounds taught?

Question

Why aren't aromatic compounds with 3, 4 or 5 carbon atoms taught at high school level chemistry? We are instead directly taught about aromatic compounds with 6 carbons/benzene rings. Why? My core question is: is because the lower members are tough to understand? Do they have any strange properties?

Answer 1

For the purpose of introducing relevant chemistry concepts and real-world scenarios, benzene is discussed in high school chemistry class. Its six-carbon structure is more stable than the 3-,4-, and 5-carbon structures and is involved in biological reactions. In academia and in the industry, 3,4, and 5 ring structures are rarely used due to their instability caused by their constrained arrangement.
