In the Hofmann bromamide degradation reaction, the number of moles of NaOH and Br2 used per mole of amine produced are: (1) One mole of NaOH and one mole of Br2. (2) Four moles of NaOH and two moles of Br2. (3) Two moles of NaOH and two moles of Br2. (4) Four moles of NaOH and one mole of Br2.

1. One mole of NaOH and one mole of Br2.
2. Four moles of NaOH and two moles of Br2.
3. Two moles of NaOH and two moles of Br2.
4. Four moles of NaOH and one mole of Br2.

Correct answer: Four moles of NaOH and one mole of Br2.

Solution

The Hofmann bromamide degradation reaction requires four moles of NaOH to effectively convert the amide to an amine, while only one mole of Br2 is needed for the bromination step, making option D the correct choice.
