Chemistry-Diazonium Salts
NEET Chemistry Diazonium Salts 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) 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
Choose the correct matching:
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.
