Lewisacidbasetheorie
Lewis acid-base theory, proposed by Gilbert N. Lewis in 1923, is a fundamental concept in chemistry that describes acid-base reactions in terms of electron pair sharing and transfer. According to Lewis, an acid is a substance that can accept an electron pair to form a covalent bond, while a base is a substance that can donate an electron pair to form a covalent bond. This theory broadens the traditional definition of acids and bases, which are typically defined as Arrhenius acids (proton donors) and bases (proton acceptors) or Bronsted-Lowry acids (proton donors) and bases (proton acceptors).
In Lewis acid-base theory, the acid-base reaction can be represented as AB + CD → AD + CB, where
Lewis acid-base theory is also applicable to coordination compounds, where the central metal ion acts as a
The Lewis acid-base theory is a versatile and widely accepted concept in chemistry, providing a comprehensive
