NEET Chemistry Organic Preparations Assertion Reason Question
Assertion (A): The addition of MnO2 to a reaction mixture containing NaI and concentrated H2SO4 results in dense violet vapors.
Reason (R): MnO2 acts as a catalyst that facilitates the oxidation of iodide ions to iodine in the reaction mixture.
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 but (R) is true.
