| Column-I | Column-II |
|---|---|
| (a) Charcoal cavity test | (i) White precipitate of zinc hydroxide |
| (b) Zinc confirmation test | (ii) White crystalline precipitate of magnesium ammonium phosphate |
| (c) Magnesium confirmation test | (iii) Coloured residue from metallic carbonate |
| (d) Bromide ion test | (iv) Orange brown color in organic layer |
A
a-iii, b-i, c-ii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iii, b-ii, c-i, d-iv
D
a-ii, b-i, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
The charcoal cavity test results in a coloured residue from the decomposition of metallic carbonate. The zinc confirmation test produces a white precipitate of zinc hydroxide. The magnesium confirmation test yields a white crystalline precipitate of magnesium ammonium phosphate. The bromide ion test shows an orange brown color in the organic layer due to bromine dissolution.
