2. Clar's rule - Wikipedia

   en.wikipedia.org/wiki/Clar's_rule

   In organic and physical organic chemistry, Clar's rule is an empirical rule that relates the chemical stability of a molecule to its aromaticity.It was introduced in 1972 by the Austrian organic chemist Erich Clar in his book The Aromatic Sextet.

3. Benzene (data page) - Wikipedia

   en.wikipedia.org/wiki/Benzene_(data_page)

   *** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available. If benzene must be used in an experiment, it should be handled at all stages in a fume cupboard.

4. Valley of stability - Wikipedia

   The chart of those nuclides is also known as a Segrè chart, after the physicist Emilio Segrè. [3] The Segrè chart may be considered a map of the nuclear valley. The region of proton and neutron combinations outside of the valley of stability is referred to as the sea of instability. [4] [5]

6. Chemical stability - Wikipedia

   en.wikipedia.org/wiki/Chemical_stability

   In chemistry, chemical stability is the thermodynamic stability of a chemical system, in particular a chemical compound or a polymer. [ 1 ] Thermodynamic stability occurs when a system is in its lowest energy state , or in chemical equilibrium with its environment.

9. Hückel's rule - Wikipedia

   en.wikipedia.org/wiki/Hückel's_rule

   The best-known example is benzene (C 6 H 6) with a conjugated system of six π electrons, which equals 4n + 2 for n = 1. The molecule undergoes substitution reactions which preserve the six π electron system rather than addition reactions which would destroy it. The stability of this π electron system is referred to as aromaticity. Still, in ...
