NEET Chemistry Organic Preparations MCQ Question
If 0.2 moles of NaI completely react with excess MnO2 and H2SO4, how many moles of I2 are produced?
0.1
0.2
0.4
0.3
Correct Answer
Detailed Explanation
The reaction 2NaI + MnO2 + 2H2SO4 → I2 + MnSO4 + Na2SO4 + 2H2O shows that 2 moles of NaI produce 1 mole of I2. Therefore, 0.2 moles of NaI will produce 0.1 moles of I2.
