Periodic trends - Wikipedia

In organic chemistry, electronegativity is associated more with different functional groups than with individual atoms. The terms group electronegativity and substituent electronegativity are used synonymously. However, it is common to distinguish between the inductive effect and the resonance effect, which might be described as σ- and π-electronegativities, respectively. There are a number of linear free-energy relationships that have been used to quantify these effects, o… WebAug 23, 2024 · Electronegativity is a measure of the affinity a nucleus has for outer shell electrons (Table 1.2).
