List of lewis bases
WebIntroduction. The Brønsted-Lowry acid-base theory is still used extensively, but it is very restrictive as it focuses primarily on acids and bases acting as proton donors and … WebIn the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, that can accept a pair …
