Question

The quantity of electricity in faradays required to reduce 1.23 gm of nitro benzene to aniline is:

• A. 0.12
• B. 0.03
• C. 0.06
• D. 0.6

Answer 1

The correct option is C 0.06

$\therefore \text{Amount of nitro benzene}=\frac{1.23}{\text{Mass of Ph-NO\_2}}$
$=\frac{1.23}{6\times 12+5+2\times 16+14}$
$=\frac{1.23}{123}=0.01$
1 mole $Ph-N{O}_2$ requires 6 moles $e^{-}$
$\therefore$ 0.01 mole $Ph-N{O}_2$ requires 0.06 mole of $e^{-}$
