NEET Chemistry Organic Preparations Assertion Reason Question
Assertion (A): Violet vapours become dense upon adding MnO2 to the reaction mixture containing NaI and H2SO4.
Reason (R): MnO2 acts as an oxidizing agent, facilitating the release of iodine from iodide ions.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
Adding MnO2 to a mixture of NaI and H2SO4 results in the formation of I2, which appears as dense violet vapours. MnO2 acts as an oxidizing agent, facilitating the oxidation of iodide ions to iodine.
