NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Carbonate ion | (i) Rotten egg smell on reaction |
| (b) Sulphide ion | (ii) Effervescence with CO2 evolution |
| (c) Borax Bead Test | (iii) Formation of a colourless bead |
| (d) Acetate ion | (iv) Deep red color with ferric chloride |
A
a-ii, b-i, c-iii, d-iv
B
a-iv, b-ii, c-i, d-iii
C
a-i, b-ii, c-iv, d-iii
D
a-ii, b-iv, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
The correct matching reflects the identification tests for specific ions. The carbonate ion produces effervescence with dilute sulfuric acid due to CO2 evolution, while the sulphide ion releases hydrogen sulphide, which has a rotten egg smell. The borax bead test is used to form a colourless bead, and the acetate ion gives a deep red color with ferric chloride as per the NCERT context.
