The major product (70% to 8%) of the reaction between m-dinitrobenzene with NH4HS is
Consider the following reaction What is Y?
Zn/NH4Cl
Reduction of nitrobenzene in the presence of Zn / NH4Cl gives
C6H5 - N = O
C6H5NH - NHC6H5
C6H5 - N = N - C6H5
O ↑C6H5 - N = N - C6H5
Attacking species in nitration of benzene in presence of fuming HNO3 is
In the above sequence, Y can be
