NEET Chemistry Organic Preparations MCQ Question
Which of the following combinations correctly describe the reactions involved in organic preparations with iodide ions?
The addition of MnO2 produces violet vapors, and in the presence of chlorine water, a violet color appears in the organic layer.
Heating iodide with concentrated sulfuric acid results in a white precipitate, and the presence of iodide ions is confirmed by a yellow solution.
Iodide ions react with sodium carbonate to form a blue solution, and the addition of sulfuric acid yields a dense green gas.
Adding excess chlorine to a sodium iodide solution leads to a colorless solution, and heating produces a yellow precipitate.
Correct Answer
Detailed Explanation
The reaction of iodide ions with MnO2 produces dense violet vapors, and when chlorine water is added, the iodine dissolves in the organic layer, resulting in a violet coloration.
