JEE MAIN - Chemistry (2022 - 27th June Morning Shift - No. 9)
Given below are two statements :
Statement I : In Hofmann degradation reaction, the migration of only an alkyl group takes place from carbonyl carbon of the amide to the nitrogen atom.
Statement II : The group is migrated in Hofmann degradation reaction to electron deficient atom.
In the light of the above statements, choose the most appropriate answer from the options given below :
Both Statement I and Statement II are correct.
Both Statement I and Statement II are incorrect.
Statement I is correct but Statement II is incorrect.
Statement I is incorrect but Statement II is correct.
Explanation
Hofmann bromamide degradation
In this degradation, the migration of the alkyl/aryl group occurs to the electron-deficient nitrogen (nitrene).
Statement (I) is not absolutely correct as it mentions only the alkyl group, whereas migration of aryl groups may also occur depending on migratory aptitude.
Statement (II) is correct as the migration occurs to the electron-deficient atom.
In this degradation, the migration of the alkyl/aryl group occurs to the electron-deficient nitrogen (nitrene).
Statement (I) is not absolutely correct as it mentions only the alkyl group, whereas migration of aryl groups may also occur depending on migratory aptitude.
Statement (II) is correct as the migration occurs to the electron-deficient atom.
