Why do pi electrons in a benzene move?
I don t understand.Pi electrons are more movable,aren t they?This is princip of the resonance,isn it?Pi electrons can easily move.Correct me if I am wrong.alxm said:In what sense? They don't really move more or less than other electrons. (unless there's a magnetic field, in which case you get a ring current, which is cool)

Delocalised pi electrons refer to the electrons that are not bound to a specific atom in a molecule, but instead are spread out over a larger area. In benzene, the six pi electrons are delocalised and move freely throughout the ring structure.
The delocalised pi electrons in benzene contribute to the molecule's stability and resonance. This allows for the six carbon atoms to be in a planar, hexagonal shape, rather than alternating between single and double bonds like in other unsaturated hydrocarbons.
The delocalised pi electrons in benzene play a crucial role in its unique chemical and physical properties. These electrons make benzene highly stable and resistant to chemical reactions, as well as giving it a flat structure and unique reactivity.
The delocalised pi electrons in benzene make it less reactive than other unsaturated hydrocarbons. This is because the electrons are already in a stable, delocalised state and do not need to form more bonds. This makes benzene less likely to undergo addition reactions and more likely to undergo substitution reactions.
Yes, delocalised pi electrons can be found in other aromatic compounds, such as toluene and naphthalene. They can also be found in other molecules with conjugated double bonds, such as in carbonyl compounds and polyenes. However, the delocalisation is not always as extensive as in benzene.
