Is phenyl acidic?
Phenols 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.
What is the nature of phenyl?
Phenyl groups are closely related to benzene and can be described as a benzene ring, minus a hydrogen, which can be substituted as a functional group by any other element or compound. Phenyl groups have six carbon atoms in a hexagonal planar structure, of which five are bonded to hydrogen atoms.
Why are phenols acidic?
Phenols are acidic because they produce phenoxides and lose hydrogen ions. The hydroxyl group in the benzoyl group has an electron-withdrawing unit that is directly connected to carbon. The electronegativity of hydroxyl groups is higher than that of benzene rings.
