उत्तर
Carbolic acid is oxidised by acidified sodium dichromate to give benzoquinone.
Explanation:
Benzoquinone is formed when carbolic acid (commonly known as phenol) is oxidized by acidified sodium dichromate. Phenols slowly oxidize in the presence of oxygen, resulting in dark-colored mixes containing quinones.
