Question

When $2$-ethylanthraquinol dissolved in a mixture of benzene and cyclohexanol is oxidized, the product is:

• A. Ethanol
• B. Hydrogen peroxide
• C. Anthracene
• D. None of these

Answer 1

Answer: (D)

None of these

Hydrogen peroxide is obtained by the auto oxidation of ethyl anthraquinol.

2-ethylanthraquinone is dissolved in benzene and hydrogen gas is passed through the solution in the presence of Pd catalyst. 2-ethylanthraquinone gets reduced to 2-ethylanthraquinol, it is dissolved in mixture of benzene and cyclohexanol and when air is passed through, it is oxidised back to 2-ethylanthraquinone and hydrogen peroxide.
