Chemical properties of phenols
WebPhenol is formed when a hydrogen atom in a benzene molecule is replaced by the -OH group. Ether is formed when an oxygen atom is connected to two alkyl or aryl groups. In this section, we will discuss how alcohols, … WebPhenols are highly prone to electrophilic substitution reactions due to rich electron density. The hydroxyl group attached to the aromatic ring in phenol facilitates the effective delocalization of the charge in the aromatic ring. Thus, it stabilizes the arenium ion through resonance. The hydroxyl group also acts as ortho para directors.
