What is Lewis acid?
{{Acids and Bases}} The concept of '''Lewis acid''' and '''Lewis base''' is one of [[acid]]s and [[Base (chemistry)|base]]s, which is independent of the idea of ([[hydron|proton]]s donor or acceptor). [[:en:Gilbert_N._Lewis|Gilbert Newton Lewis]] developed this idea in the early 20th century. In this concept, a Lewis acid can accept and bind [[electron]]s. Lewis acid is a substance that accepts two [[electron]]s to form a [[covalent bond]].<ref>{{cite web |url= http://www.credoreference.com/entry/apdst/acid |title=Acid |first= |last= |work=Academic Press Dictionary of Science and Technology |year=2011 |accessdate=6 August 2011}}</ref> A Lewis base is a substance that gives two electrons in the bonding.<ref>{{cite web |url=http://facultyfp.salisbury.edu/dfrieck/htdocs/212/rev/acidbase/lewis.htm |title=The Lewis Acid |first= |last= |work=facultyfp.salisbury.edu |year=2009 |accessdate=6 August 2011 |archive-date=6 September 2011 |archive-url=https://web.archive.org/web/20110906010950/http://facultyfp.salisbury.edu/dfrieck/htdocs/212/rev/acidbase/lewis.htm |url-status=dead }}</ref> A Lewis acid together with a Lewis base will [[chemical reaction| react]] to make a compound called a [[Lewis adduct]]. ==References== {{reflist}} {{chem-stub}} [[Category:Chemistry]]
