Options:

Answer:

Solution:

${4 e}^{-} + 4 H^{+} + C_{6} H_{5} {NO}_{2} \to C_{6} H_{4} (OH) ({NH}_{2}) + H_{2} O$

Molecular Weight of p-aminophenol = 109 g

$W_{(D e p o s i t e d)} = Z I t$

= $\frac{E}{F} \times I \times t (E = \frac{M}{4})$

$W = \frac{109 \times 9.65 \times 60 \times 60}{4 \times 96500} = 9.81 g$
