A) Perkins reaction
B) Fries reaction
C) Libermann nitroso reaction
D) Etard reaction
Correct Answer: C
Solution :
Nitrosoamine on heating with cone.\[{{H}_{2}}S{{O}_{4}}\]gives secondary amine. This reaction is called Libermann nitroso reaction. \[\underset{nitrosoamine}{\mathop{{{R}_{2}}N-N=O}}\,+{{H}_{2}}O\xrightarrow[{}]{conc.\,{{H}_{2}}S{{O}_{4}}}\underset{\begin{smallmatrix} secondary \\ amine \end{smallmatrix}}{\mathop{{{R}_{2}}NH}}\,\] \[+HN{{O}_{2}}\]You need to login to perform this action.
