WebTeoria HSAB HSAB concetto è una sigla per "duri e molli acidi (Lewis) e basi ". Conosciuto anche come concetto acido-base di Pearson , HSAB è ampiamente utilizzato in chimica per spiegare la stabilità dei composti , i meccanismi di reazione e le vie. Assegna i termini "hard" o "soft" e "acid" o "base" alle specie chimiche . An application of HSAB theory is the so-called Kornblum's rule (after Nathan Kornblum) which states that in reactions with ambident nucleophiles (nucleophiles that can attack from two or more places), the more electronegative atom reacts when the reaction mechanism is … See more HSAB concept is a jargon for "hard and soft (Lewis) acids and bases". HSAB is widely used in chemistry for explaining stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or … See more Essentially, the theory states that soft acids react faster and form stronger bonds with soft bases, whereas hard acids react faster and form … See more If the interaction between acid and base in solution results in an equilibrium mixture the strength of the interaction can be quantified in terms of an equilibrium constant. An alternative quantitative measure is the heat (enthalpy) of formation of the … See more In 1983 Pearson together with Robert Parr extended the qualitative HSAB theory with a quantitative definition of the chemical hardness ( See more • Acid-base reaction • Oxophilicity See more

WebTeoria HSAB • Pearson chamou os íons tipo (a) de ácidos duros e os íons tipo (b) de ácidos macios. • As bases também podem ser classificadas como duras e macias. • Por exemplo, os haletos variam desde o F (base dura) até o I- (base macia). • As reações são mais favoráveis entre espécies duro-duro e macio-macio do que uma mistura duro-macio.
