Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Benzenediazonium chloride | (i) Hydrolysis to phenol |
| (b) Aryl diazonium salts | (ii) Replacement by –NO2 group |
| (c) Diazonium fluoroborate | (iii) Stability in solution |
| (d) Heating with phenol | (iv) Formation of azo dyes |
A
a-i, b-iii, c-ii, d-iv
B
a-ii, b-iv, c-i, d-iii
C
a-iv, b-i, c-iii, d-ii
D
a-iii, b-ii, c-iv, d-i
Correct Answer
Option A
Detailed Explanation
Benzenediazonium chloride hydrolyzes to phenol upon heating, while aryl diazonium salts are stable in solution. Diazonium fluoroborate can undergo a reaction to replace the diazonium group with –NO2. Heating with phenol results in the formation of azo dyes, which are colored compounds.
