Hard and soft acids and bases hsab principle
WebHard and Soft Acids and Bases . 1965- Ralph Pearson introduced the hard-soft-acid-base (HSAB) principle. “Hard acids prefer to coordinate the hard bases and soft acids to soft bases” This very simple concept was used by Pearson to rationalize a variety of chemical information. 1983 – the qualitative definition of HSAB was WebAbstract: The principle of hard and soft acid and bases (HSAB principle) is applied to organic chemistry. ,Organic molecules are viewed as Lewis acid-base complexes and their relative thermodynamic stability explained in terms of two factors. One is the tendency of intrinsically strong acids to coordinate to the strongest bases. The
