NEET Chemistry Functional Group Tests Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Lead ion test | (i) Potassium hexanitritocobaltate(III) |
| (b) Cobalt ion test | (ii) Brown precipitate of basic mercury amido-iodine |
| (c) Mercury ion test | (iii) Yellow precipitate formation |
| (d) Group I cations | (iv) White precipitate appearance |
a-iv, b-iii, c-ii, d-i
a-iii, b-i, c-iv, d-ii
a-ii, b-iv, c-iii, d-i
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
The lead ion test involves observing a white precipitate, the cobalt ion test results in a yellow precipitate of potassium hexanitritocobaltate(III), and the mercury ion test yields a brown precipitate of basic mercury amido-iodine. Group I cations are characterized by the appearance of a white precipitate when treated with dilute HCl.
