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 … WebSigma bonds are stronger than pi-bonds. Shared electron pair in a sigma bond is closer to the positively charged nuclei of both atoms, meaning a stronger force of attraction …
