Statement I: Number of Faraday’s required for the conversion of nitrobenzene to aniline is 8
Statement II: Change in oxidation number is 6
Answer & explanation
Correct answer: option 4
The answer is 4. Statement I is false but Statement II is correct.
Statement I is false because the number of Faraday's required for the conversion of nitrobenzene to aniline is 6, not 8. This is because the oxidation number of nitrogen in nitrobenzene is +3, and the oxidation number of nitrogen in aniline is -1. Therefore, 6 electrons are required to reduce the nitrogen atom in nitrobenzene to aniline.
Statement II is correct because the change in oxidation number is 6. This is the number of electrons that are transferred during the reaction.
