RE-NEET 2024 Chemistry Anion Detection Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match List-I with List-II:
| Solid salt treated with dil. H₂SO₄ | Anion detected |
|---|---|
| (A) effervescence of colourless gas | (I) NO₂⁻ |
| (B) gas with smell of rotten egg | (II) CO₃²⁻ |
| (C) gas with pungent smell | (III) S²⁻ |
| (D) brown fumes | (IV) SO₃²⁻ |
A
A⁻II, B⁻III, C⁻IV, D⁻I
B
A⁻IV, B⁻III, C⁻II, D⁻I
C
A⁻I, B⁻II, C⁻III, D⁻IV
D
A⁻II, B⁻III, C⁻I, D⁻IV
Correct Answer
Option A
Detailed Explanation
Effervescence of a colorless gas indicates CO₃²⁻ (A⁻II). Rotten egg smell is characteristic of H₂S from S²⁻ (B⁻III). Pungent smell indicates SO₂ from SO₃²⁻ (C⁻IV). Brown fumes are due to NO₂⁻ (D⁻I).
