Document Summary
The lewis and the br nsted lowry concepts are simply different ways of looking at certain chemical reactions. Such different views are often helpful in understanding reactions. Certain reactions have the characteristics of acid base reactions but do not fit the. The br nsted theory defines acids and bases as proton donors and acceptors. Around the same time that johannes n. br nsted and thomas m. lowry came up with their theory of acids and bases, gilbert n. lewis proposed his own theory. While the br nsted-lowry theory is based on the transfer of protons, lewis" theory is based on the transfer of electrons. A lewis acid is a substance that can accept a pair of electrons to form a new bond. They are sometimes referred to as electrophiles, or seekers of an additional electron pair. A lewis base is a substance that can donate a pair of electrons to form a new bond.
