Question

In the Hofmann bromamide degradation reaction, the number of moles of NaOH and Br2 used per mole of amine produced are:

  • Four moles of NaOH and two moles of Br2

  • Two moles of NaOH and two moles of Br2

  • Four moles of NaOH and one mole of Br2

  • One mole of NaOH and one mole of Br2

Answer

C.

Four moles of NaOH and one mole of Br2

Hofmann-bromamide degradation reaction is given as
RCONH2 + 4 NaOH + Br2 → RNH2 + Na2CO3 + 2NaBr + 2H2O
Hence four moles of NaOH and one mole of Br2 are used.
