####16. In the Hofmann-bromamide degradation reaction, the number of moles of NaOH and Br2 used per mole of amine produced are

(2016 Main)

(a) four moles of NaOH and two moles of Br2

(b) two moles of NaOH and two moles of Br2

(c) four moles of NaOH and one mole of Br2

(d) one mole of NaOH and one mole of Br2

Show Answer

Answer:

Correct Answer: 16. (c)

Solution:

  1. Hofmann-bromamide degradation reaction is given as:
