NEET Chemistry Organic Preparations Assertion Reason Question
Assertion (A): The addition of MnO2 to a reaction mixture containing NaI and H2SO4 results in the formation of dense violet vapours. | Reason (R): MnO2 facilitates the oxidation of iodide ions to iodine, which dissolves in organic solvents to produce violet colouration.
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
The addition of MnO2 to a reaction mixture containing NaI and H2SO4 leads to the formation of iodine, which results in dense violet vapours. MnO2 aids in the oxidation of iodide ions to iodine, confirming the reason explains the assertion.
