Explanation of sigma and pi bonds

WebDec 17, 2024 · N X 2 has three bonds between the two atoms N : one sigma and two pi. One of these bonds has to loose one electron to form N X 2 X +. Apparently it is the sigma bond. As a consequence, this bond still exists and becomes a one-electron bond, or a half sigma bond Dec 17, 2024 at 15:55 1 chemistry.stackexchange.com/questions/11007/… – WebJan 23, 2024 · This extensive sideways overlap produces a system of pi bonds which are spread out over the whole carbon ring. Because the electrons are no longer held between just two carbon atoms, but are spread over the whole ring, the electrons are said to be delocalized. The six delocalized electrons go into three molecular orbitals - two in each.
