NEET Chemistry Organic Preparations Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Chlorine gas evolution | (i) Violet color in organic layer |
| (b) White precipitate formation | (ii) Yellow gas with NaOH |
| (c) Iodide ion detection | (iii) Curdy white precipitate |
| (d) Sulfur dioxide evolution | (iv) Greenish yellow gas |
a-iv, b-iii, c-i, d-ii
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
The evolution of chlorine gas is confirmed by its greenish yellow color (a-iv), while a curdy white precipitate confirms the presence of chloride ions (b-iii). The presence of iodide ions is indicated by the violet color in the organic layer (c-i), and the yellow gas formed with NaOH indicates sulfur dioxide evolution (d-ii).
