WebOrganic Ph. Ch. Practice Dr.Sawsan Lab:5 Date:1/4/2024. Practical Organic Pharmaceutical Chemistry II Synthesis of Phenol Phenol is a compound in which one of the hydrogen atoms of the ... The product of this reaction is sodium phenoxide, which is acidified with aqueous acid to yield phenol. WebOn the basis of our studies of this compound with more specific oxidizing radicals such as N3, Tl(II), etc. it was inferred that hydroxyl radicals lead mainly to one electron oxidation at pH 10 where BP is present as the phenoxide ion. Whereas at pH 5 (phenolic form), oxidation is only a minor process, the major being the formation of addition ...
