I. Primary aliphatic amines react with HNO2 to give unstable diazonium salts.
II. Primary aromatic amines react with HNO2 to form diazonium salts which are stable even above 300 K.In the light of the above statements, choose the most appropriate answer from the options given below:
  • a)
    I is incorrect but II is correct
  • b)
    Both I and II are correct
  • c)
    Both I and II are incorrect
  • d)
    I is correct but II is incorrect
Correct answer is option 'D'. Can you explain this answer?

Statement Analysis:

I. Primary aliphatic amines react with HNO2 to give unstable diazonium salts.
II. Primary aromatic amines react with HNO2 to form diazonium salts which are stable even above 300 K.

Explanation:

Diazonium salts are formed by the reaction of primary amines with nitrous acid (HNO2). These salts are unstable in nature and are used as intermediates in many organic reactions.

Statement I is correct as primary aliphatic amines react with HNO2 to give unstable diazonium salts, which decompose rapidly to form carbocations and nitrogen gas.

On the other hand, statement II is incorrect as primary aromatic amines react with HNO2 to form diazonium salts which are unstable and decompose easily. However, these salts can be stabilized by the presence of electron-donating groups on the aromatic ring. The stability of diazonium salts increases with the increase in the number of electron-donating groups on the aromatic ring.

Therefore, the correct option is D, i.e., I is correct but II is incorrect.

Given below are two statements:I. Primary aliphatic amines react with...
Primary aliphatic amines react with nitrous acid to form aliphatic diazonium salts which are unstable, and liberate nitrogen gas quantitatively and alcohols.
The reactions are as follows:
Primary aromatic amines form arenediazonium salts which are stable for a short time in solution at low temperatures (273-278 K). Thus, Primary aromatic amines react with HNO2 to form diazonium salts which are stable even above 300 K is a wrong statement.
Thus, option 4th is the correct answer.
