Phenol to nitrophenol
Nitrophenols are compounds of the formula HOC6H5−x(NO2)x. The conjugate bases are called nitrophenolates. Nitrophenols are more acidic than phenol itself. Web23. jan 2024 · Phenol burns in a plentiful supply of oxygen to give carbon dioxide and water. (1) C 6 H 5 O H + 7 O 2 → 6 C O 2 + 3 H 2 O. However, for compounds containing benzene rings, combustion is hardly ever complete, especially if they are burnt in air. The high proportion of carbon in phenol means that you need a very high proportion of oxygen to ...
