How many faradays are required for reduction of 1mol ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NO}}_2$ into ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NH}}_2?$

Thus, the reduction of 1 mole of nitrobenzene to 1 mole of aniline requires 6 moles of electrons. Hence, six faradays are required for the reduction of 1 mol C₆H₅NO₂ into C₆H₅NH₂. The correct answer is 6.
