CBSE Class 12 · 2002 · All India Compartment · Compounds Containing NitrogenShort Answer

Write the reactions involved in obtaining p-aminoazobenzene using only nitrobenzene as the organic starting reagent.

Solution

1.

C_{6} H_{5} N O_{2} + 6 [H] Sn/HCl C_{6} H_{5} N H_{2}

2.

C_{6} H_{5} N H_{2} NaN O_{2} /HCl, 273K C_{6} H_{5} N_{2}^{+} C l^{-}

3.

C_{6} H_{5} N_{2}^{+} C l^{-} + C_{6} H_{5} N H_{2} \to C_{6} H_{5} N = N - C_{6} H_{4} N H_{2} (p) + HCl
