(i) $C H_{3} B r K C N - ------ \to A L i A l H_{4} - ------- \to B H N O_{2} - ------- \to 273 K C$
(ii) $C H_{3} C O O H N H_{3} - ------ \to Δ A {B r}_{2} + K O H - --------- \to B C H {C l}_{3} + N a O H - ------------ \to C$

Solution

(i) $C H_{3} B r K C N - -- \to C H_{3} C N L i A l H_{4} - --- \to C H_{3} C H_{2} N H_{2} H N O_{3} - --- \to 273 K C H_{3} C H_{2} - O H$

(ii) $C H_{3} C O O H N H_{3} - -- \to Δ C H_{3} C O N H_{2} B r_{2} + K O H - ------ \to C H_{3} N H_{2} C H C l_{3} + N a O H - -------- \to C H_{3} N C$
