Hypervalent boron
WebHypervalent systems based on sulfur, phosphorus, iodine, and other main group elements in the third row or lower of the periodic table are numerous. By contrast, examples of hypervalent boron, carbon, and other second row elements are rare. We are exploring the possibility of preparing an isolable example of hypervalent nitrogen. WebHypervalent molecules have a central atom that has more electrons than needed for a noble gas configuration. Odd-electron Molecules We call molecules that contain an odd number of electrons free radicals.
