The major product (70% to 8%) of the reaction between m-dinitrobenzene with NH4HS is
In the reduction of nitrobenzene, which of the following is the intermediate?
C6H5 - N = O
C6H5NH - NHC6H5
C6H5 - N = N - C6H5
O ↑C6H5 - N = N - C6H5
Tertiary nitro compounds do not tautomerise because
There is no double bond
There is no α - hydrogen
Oxygen is more electronegative than hydrogen
All of the above
In the above sequence, Y can be
4 - Nitrochlorobenzene
I - Nitrochlorobenzene
3 - Nitrochlorobenzene
None of the these
Attacking species in nitration of benzene in presence of fuming HNO3 is
SO3
Nitrobenzene on further excessive nitration gives
sym - Trinitrobenzene
m - Dinitrobenzene
p - Dinitrobenzene
All of these
Reduction of nitrobenzene in the presence of Zn / NH4Cl gives
Azobenzene
Aniline
N - phenylhydroxylamine
Hydrazobenzene
The reagent that reacts with nitromethane to form methylhydroxylamine is
Zn/HCl
Zn/NH4Cl
Zn/NaOH
Sn/HCl
Consider the following reaction What is Y?
Acetanilide
Benzanilide
