Passage / Comprehension

Adiponitrile (C₆H₈N₂), a key intermedate in the manfacture of nylon, is made industrially by an electrolysis process that reduces acrylonitrile and oxidizes water.

How many charge (in faraday) required to produce 204 gram of adiponitrile : (Given current efficiency is $80%$ )

Options:

Answer:

Solution:

At cathode

$2 CH_{2} = CHCN + 2 H^{+} + 2 e^{-} \to NC (CH_{2})_{4} CN$

Acrylonitrile Adiponitrile

Charge required for 2 mole adiponitrile ⟶ 4F

As we know current efficiency is $80%$ then $Q \times 0.8 = 4 (Q = 5 F)$
