NEET Chemistry (general) Match the Following Question
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
Choose the correct matching:
a-ii, b-i, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
Correct Answer
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.
