When 9.65 ampere current was passed for 1.0 hour into nitrobenzene in acidic medium, the amount of p-amino-phenol produced is....... [JEE-Main On line-2018]

1. 109.0 g
2. 98.1 g
3. 9.81 g
4. 10.9 g

Correct answer: 9.81 g

Solution

The correct option is derived from Faraday's laws of electrolysis, where the amount of substance produced is directly proportional to the electric charge passed through the solution. Given the current and time, the total charge can be calculated, and using the molar mass of p-amino-phenol, the amount produced can be determined, resulting in 9.81 g.
