Phenol charge
WebPhenols are organic compounds containing a benzene ring bonded to a hydroxyl group. They are also known as carbolic acids. Phenols react with active metals like sodium, and potassium to form phenoxide. This reaction of phenol with metals indicates its acidic nature. Phenols react with aqueous sodium hydroxide too to produce phenoxide ions. WebNov 14, 2024 · Here the negative charge of oxygen after releasing hydrogen atom dispersed the aromatic ring and thus stabilize. Chemical properties. Phenol undergoes electrophilic substitution reaction more readily than benzene. Using the same reaction condition when benzene gives mono-substituted product, phenol gives tri-substituted phenol.
