Amines - Result Question 32

####34. Intermediates formed during reaction of

$\underset{O}{R C N H_{2}} with B r_{2} and K O H are$

(a) $R N H B r$ and $R C O N H B r$

(b) $R N H C O B r$ and $R N C O$

(d) $R C O N B r_{2}$

Show Answer

Solution:

(i) $R C O N H_{2} + B r_{2} \to R C O N H B r + H B r$

(ii) $R C O N H B r + H B r \overset{O H^{-}}{\to}$

$R - C O \ddot{N} B r + H_{2} O$ (iii)

(iv)

(v) $R - \ddot{N} = C = O + 2 K O H \to R N H_{2} + K_{2} C O_{3}$
