RCONH 2 is converted into RNH 2 by means of Hofmann's bromamide degradation. In this reaction, RCONHBr is formed from which this reaction has derived its name. Electron donating group at phenyl activates the reaction. Hofmann's degradation reaction is an intramolecular reaction. (2006,3 × 4 M =12 M ) How can the conversion of (i) to (ii) be brought about?

Correct answer is (d) Br2 + KOH

KBr

$K B r + C H_{3} ON a$

$K B r + K O H$

$B r_{2} + K O H$

Correct answer is (d) $B r_{2} + K O H$

KBr

KBr+CH3​ONa

KBr+KOH

Br2​+KOH

Correct answer is (d) Br2​+KOH

$K B r + C H_{3} ON a$

$K B r + K O H$

$B r_{2} + K O H$

Correct answer is (d) $B r_{2} + K O H$
