NEET Chemistry Diazonium Salts MCQ Question
Which of the following statements about diazonium salts is correct?
Diazonium salts are stable at room temperature and can easily be hydrolyzed.
Benzenediazonium chloride is a colorless crystalline solid that is insoluble in water.
Primary aromatic amines form stable arenediazonium salts that can be used in dye synthesis.
The diazonium group is a good leaving group that facilitates substitution reactions with various anions.
Correct Answer
Detailed Explanation
The diazonium group is indeed a very good leaving group, allowing for substitution reactions where it can be replaced by other groups like Cl–, Br–, and OH–, as mentioned in the context. Additionally, benzenediazonium chloride is soluble in water and not insoluble, while primary aromatic amines form arenediazonium salts that are stable only for a short time at low temperatures.
