Directions: In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.
Assertion: Hoffmann's bromamide reaction is given by primary amines.
Reason: Primary amines are more basic than secondary amines.
Reason: Primary amines are more basic than secondary amines.
- a)If both A and R are true and R is the correct explanation of A
- b)If both A and R are true but R is NOT the correct explanation of A
- c)If A is true but R is false
- d)If Both A and R is False
Correct answer is option 'D'. Can you explain this answer?

The Hoffmann bromamide degradation reaction prepares primary amines by treating an amide with bromine in an aqueous or ethanolic sodium hydroxide solution. The resulting amine has one carbon atom less than the original amide.
Therefore, the assertion is incorrect because Hoffmann’s bromamide reaction involves amides rather than primary amines, even though the product is a primary amine.
Reason:
Primary amines are less basic than secondary amines because secondary amines have more electron-donating alkyl groups, which enhance their basicity. Thus, the reason statement is also incorrect.
Primary amines are less basic than secondary amines because secondary amines have more electron-donating alkyl groups, which enhance their basicity. Thus, the reason statement is also incorrect.
Consequently, both the assertion and reason are wrong.

Understanding the Assertion and Reason
The question presents two statements regarding Hoffmann's bromamide reaction and the basicity of amines. Let's analyze both parts:
Assertion (A): Hoffmann's bromamide reaction is given by primary amines.
- Hoffmann's bromamide reaction specifically involves the conversion of primary amides to primary amines using bromine and a strong base, typically sodium hydroxide.
- However, this reaction does not occur with primary amines directly; it is the amides that participate in this reaction.
Reason (R): Primary amines are more basic than secondary amines.
- This statement is generally true. Primary amines tend to be more basic than secondary amines due to the presence of electron-donating alkyl groups, which enhance the availability of the lone pair of electrons on the nitrogen atom.
- That said, the basicity of amines is not the reason for the occurrence of Hoffmann's bromamide reaction.
Conclusion: Why the Correct Answer is D
- Both statements are not true in the context provided. The assertion is incorrect because Hoffmann's bromamide reaction involves primary amides, not primary amines.
- The reason, while true in a general sense regarding basicity, does not correlate to the assertion about Hoffmann's bromamide reaction.
Final Answer
Thus, the correct choice is option 'D' because both the assertion and the reason are false in the context of the question.
