When 9.65 ampere current was passed for 1.0 hour into nitrobenzene in acidic medium, the amount of p-aminophenol produced is:When 9.65 ampere current was passed for 1.0 hour into nitrobenzene in acidic medium, the amount of p-aminophenol

Options

  1. A109.0 g
  2. B98.1 g
  3. C9.81 g
  4. D10.9 g

Correct answer

C. 9.81 g

Step-by-step solution

When 9.65 ampere current was passed for 1.0 hour into nitrobenzene in acidic medium, the amount of p-aminophenol

4e−+4H++C6H5NO2→C6H4(OH)(NH2)+H2O{4e}^{-} + 4{H}^{+} + {C}_{6}{H}_{5}{NO}_{2} \to {C}_{6}{H}_{4}\left(OH\right)\left({NH}_{2}\right) + {H}_{2}O

Molecular Weight of p-aminophenol = 109 g

W(Deposited)=ZIt{W}_{( Deposited )} \text{=}ZIt

=EF×I×t(E=M4)\dfrac{E}{F} \times I \times t\left(E = \dfrac{M}{4}\right)

W=109×9.65×60×604×96500=9.81gW = \dfrac{109 \times 9.65 \times 60 \times 60}{4 \times 96500} = 9.81g
