Question

Give the structures of A, B and C in the following reactions :

(i) $C_{6} H_{5} N O_{2} S n + H C l - ---- \to A N a N O_{2} + H C l - ------- \to 273 K B H_{2} O - - \to C$

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

Open in App

Solution

(i)
$A = C_{6} H_{5} N H_{2}$
$B = C_{6} H_{5} -_{2} C l^{-}$
$C = C_{6} H_{5} - O H$

(ii)
$A = C H_{3} C O O H$
$B = C H_{3} C O N H_{2}$
$C = C H_{3} N H_{2}$
