WebEthane. The electron pair in a σ bond is found in a region of space between the nuclei of the two atoms that are sharing the electrons; The electrostatic attraction between the electrons (negatively charged) and the two nuclei (positively charged) holds the two atoms together; … WebAs electronegativity difference increases, the decrease in energy of the sigma bond is greatest, forming the more homolytically stable bonds. The extreme of this is formation of an anion and cation, where an equal split of the “bonding” pair of electrons doesn’t happen by definition, thus a homolytic BDE equal to the enthalpy of the ion formation process, but … high protein breakfast foods for diabetics
