Web12. apr 2024 · Phenol is an aromatic organic compound with the molecular formula C 6 H 5 O H. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group ( − C 6 H 6) bonded to a hydroxyl group (−OH). Mildly acidic, it requires careful handling because it can cause chemical burns. WebExplain why the phenol -OH rather than the carboxylic acid -OH of salicylic acid is acetylated by acetic anhydride. Hint: Think about the reactivity of these two groups. The phenol -OHH …
WebPhenol is a strong acid that is consistent with the ECW model’s C/E ratio with EA = 2.27 and CA = 1.07; Oxidation – Phenols undergo oxidation, like other alcohols, but have distinct forms of properties than those seen in aliphatic alcohols. For starters, most phenols are oxidized by chromic acid into conjugated 1,4-diketones called quinones.
