NEET Chemistry Functional Group Tests Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Copper ion test | (i) Yellow precipitate of potassium hexanitritocobaltate(III) |
| (b) Cobalt ion test | (ii) Deep blue solution of tetraamminecopper(II) sulphate |
| (c) Acidification effect | (iii) Formation of sulphate from sulphur |
| (d) Basic copper sulphate | (iv) Formation of tetraamminecopper(II) complex |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
a-iii, b-ii, c-i, d-iv
Correct Answer
Detailed Explanation
The correct matching indicates that the copper ion test yields a deep blue solution of tetraamminecopper(II) sulphate, while the cobalt ion test results in a yellow precipitate of potassium hexanitritocobaltate(III). This is consistent with the information provided about the tests for these ions.
