Chemistry / Do we understand the covalent bond ?
« on: 18/05/2008 05:03:40 »
Maybe I'm not reading far enough into the theory, but how does this explain conjugated systems, where electrons are shown to flow freely throughout the system???
For example benzene or 1,3-butadiene where the pi electrons are thought to be dispersed throughout the entire molecule. How does this theory explain aromaticity? Why is an aromatic compound lower in energy than a non-aromatic or anti-aromatic compound??
Also how can this "new theory" explain how these conjugated systems absorb specific wavelengths of the electromagnetic spectrum, if not by quantum mechanics???
