Write one chemical equation each to exemplify the following reactions:
i) carbylamine reaction
ii) Hofmann bromamide reaction

Answer: (i) RNH₂ + CHCl₃ + 3KOH → RNC + 3KCl + 3H₂O. (ii) RCONH₂ + Br₂ + 4NaOH → RNH₂ + Na₂CO₃ + 2NaBr + 2H₂O.

Solution

(i)

C_{6} H_{5} N H_{2} + CHC l_{3} + 3KOH Δ C_{6} H_{5} NC + 3KCl + 3 H_{2} O

(ii)

C H_{3} CON H_{2} + B r_{2} + 4NaOH \to C H_{3} N H_{2} + N a_{2} C O_{3} + 2NaBr + 2 H_{2} O
