Which reagent is used for selective reduction of m-dinitrobenzene?
Which reagent is used for selective reduction of m-dinitrobenzene?
This selective reduction can be achieved by boiling an aqueous suspension of m-Dinitrobenzene with sodium disulphide. Sodium disulphide is prepared in situ by the addition of Sulphur to sodium sulphide solution.

Which reagent is used for the conversion of m-dinitrobenzene to nitro aniline?
with ammonium sulphide (${(N{H_4})_2}S$) is the correct answer. Note: It must be noted that Sn / HCl is known as the best reagent for reduction of m- dinitrobenzene to m- nitroaniline but here it can not be used because its use will reduce both the nitro groups to amino groups.
What is the reagent best required for preparation of M dinitrobenzene from nitrobenzene?
Step 1: Preparation of m-dinitrobenzene from nitrobenzene Place 37.5 g (21 ml) of concentrated sulphuric acid and 22.5 g (15 ml) of fuming nitric acid, in a round-bottomed flask; add few fragents of porcelain pieces. Attach a reflux condenser and place the apparatus in a fume cupboard.
How is selective reduction performed?
Once the specific fetuses to be reduced are identified, potassium chloride is injected into the heart of each selected fetus under the guidance of ultrasound imaging; the heart stops and the fetus dies as a result. Generally, the fetal material is reabsorbed into the woman’s body.
What is the density of nitrobenzene?
1.2 g/cm³
Nitrobenzene/Density
What is the reaction mechanism for synthesis of M dinitrobenzene from nitrobenzene?
It is an electrophilic aromatic substitution in presence of NO2, which is a strong electron withdrawing group and it directs the incoming substituents to the meta position. Here nitronium ions act as the electrophile which is generated from fuming nitric acid in presence of conc. sulphuric acid.
What is the structure of M-nitroaniline?
C6H6N2O2
3-Nitroaniline/Formula
Is M-nitroaniline a base?
Bases (e.g., m-nitroaniline, which is a base because it is a proton acceptor) become positively charged when reacted with an acid, and this positively charged ion will now partition into the aqueous layer. Charged molecules partition into the aqueous layer and uncharged molecules partition into the organic layer.
Which of the following is used as a reagent for the nitration of benzene to nitrobenzene?
The major reagent which is used in the nitration of benzene is HNO3. It is an electrophilic reaction of Benzene. H2SO4 is also used as a mixture with HNO3 as here H2SO4 act as a catalyst.
Is selective reduction abortion?
Selective reduction and abortion both involve the termination of fetal life, but they are classified by different designations to underscore the notion that they are regarded as fundamentally different medical procedures: the two are performed using distinct techniques by different types of physicians, upon women under …
