Given below are two statements:
Statement I:
Primary aliphatic amines react with to give unstable diazonium salts.
Statement II :
Primary aromatic amines react with to form diazonium salts which are stable even above . In the light of the above statements, choose the most appropriate answer from the options given below
Statement I:
Primary aliphatic amines react with to give unstable diazonium salts.
Statement II :
Primary aromatic amines react with to form diazonium salts which are stable even above . In the light of the above statements, choose the most appropriate answer from the options given below
Options
- ABoth Statements and Statement are is incorrect.
- BStatement is correct but Statement is incorrect.
- CStatement is incorrect but Statement is correct.
- DBoth Statement and Statement are correct.
Correct answer
B. Statement is correct but Statement is incorrect.
Step-by-step solution
When primary aliphatic amines react with then unstable diazonium salt, which result in the formation of alcohol and gas.
And when primary aromatic amines react with the diazonium salts formed are stable due to resonance stabilisation of the aromatic ring of aryl diazoniun salts.But these are stable only at 273-277 K, at higher temperatures they are unstable.
Hence, Statement is correct but Statement is incorrect.
