WebJan 11, 2016 · Electronegativity is a function of an atom’s ability to attract an electrons binding pair. The most frequently used is the Pauling scale. Fluorine is assigned a value of 4.0, and values that are the least electronegative at 0.7 range down to cesium and … Download free PDF here.

Its ionic and covalent radii, m.p. and b.p., bond dissociation enthalpy, and electron gain enthalpy are quite low than expected. Fluorine has an extremely small atomic size. But why does Fluorine behave so abnormally?

WebSep 24, 2024 · The structures with a negative charge on the more electronegative atom will be more stable. The difference between the two resonance structures is the placement of a negative charge. Structure B is the more stable and the major resonance contributor, because it places the negative charge on the more electronegative oxygen. 4.

The small amount of extra negative charge built up on the nitrogen atom makes the lone pair even more attractive towards hydrogen ions. Correspondingly, primary, secondary, and tertiary alkyl amines are more basic than ammonia. WebThe chemical structureof a moleculeis intimately related to its properties and reactivity.
