NEET Chemistry Organic Preparations Assertion Reason Question
Assertion (A): Adding MnO2 to a reaction mixture containing NaI and H2SO4 results in the evolution of dense violet vapors.
Reason (R): MnO2 acts as an oxidizing agent, facilitating the liberation 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.
