JEE MAIN Chemistry QUESTION #5569
Question 1
In the Hofmann bromamide degradation reaction, how many moles of NaOH and $Br_2$ are used per mole of amine produced?
  • Four moles of NaOH and two moles of $Br_2$
  • Two moles of NaOH and two moles of $Br_2$
  • Four moles of NaOH and one mole of $Br_2$✔️
  • One mole of NaOH and one mole of $Br_2$
Correct Answer Explanation
The Hofmann bromamide reaction: $RCONH_2 + Br_2 + 4NaOH \to RNH_2 + Na_2CO_3 + 2NaBr + 2H_2O$. The reaction requires 1 mole of $Br_2$ (to brominate the amide) and 4 moles of NaOH (2 to form NaOBr in situ + 2 more to complete the reaction).
