Phenol nucleophile

Webphenol, any of a family of organic compounds characterized by a hydroxyl (―OH) group attached to a carbon atom that is part of an aromatic ring. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simplest member, monohydroxybenzene (C 6 H 5 OH), also known as benzenol, or carbolic acid. WebQuestion: NaOH was used as the base to deprotonate an unknown phenol to form an alkoxide nucleophile in this weeks video. Use acid-base reactions, and pKa values OR ARIO, to explain why NaOH is a strong enough base to fully deprotonate a phenol (aromatic alcohol) but not an aliphatic alcohol?
