AIIMS 2017 Chemistry Faraday's Laws of Electrolysis MCQ Question
The number of coulombs required to reduce 12.3 g of nitrobenzene to aniline is
96500 C
5790 C
95700 C
57900 C
Correct Answer
Detailed Explanation
To determine the charge needed for the electrolysis of nitrobenzene, we use the formula , where is the number of moles and is Faraday's constant (approximately 96500 C/mol). Given that the molar mass of nitrobenzene is 123 g/mol, the charge can be calculated as , which simplifies to approximately 57900 C, confirming option B as correct. Options A, C, and D do not provide valid calculations or relevant information needed to solve the problem, making them incorrect.
