NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Heating salt in a charcoal cavity | (i) Formation of white fumes with ammonia |
| (b) Reaction with dilute HNO3 and AgNO3 | (ii) Decomposition to corresponding oxide |
| (c) Treatment with conc. H2SO4 | (iii) Presence of chloride ions |
| (d) Addition of disodium hydrogen phosphate | (iv) Formation of magnesium ammonium phosphate |
A
a-ii, b-i, c-iii, d-iv
B
a-iii, b-ii, c-iv, d-i
C
a-ii, b-iii, c-i, d-iv
D
a-i, b-iv, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
The correct pairing reflects the processes described in the NCERT context, where heating in a charcoal cavity leads to decomposition, while the reaction with dilute HNO3 and AgNO3 confirms chloride ions. Treatment with conc. H2SO4 is associated with chloride ion reactions and disodium hydrogen phosphate leads to magnesium ammonium phosphate formation.
