Is 3 nitroaniline a base?
Table of Contents
The 3-nitroaniline is an organic base; there is a lone pair of electrons on the nitrogen atom of the amino group, making 3-nitroaniline a Lewis base (an electron pair donor). Under these conditions biphenyl has neither an acidic proton nor a lone pair of electrons to donate, and is considered a neutral compound.
What is the structure of M nitroaniline?
C6H6N2O23-Nitroaniline / Formula
What is the melting point of 3 nitroaniline?
237.2°F (114°C)3-Nitroaniline / Melting point
Is M nitroaniline an acid or base?
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.

Is 3-nitroaniline flammable?
ICSC 0307 – 3-NITROANILINE. Combustible. Many reactions may cause fire or explosion. Finely dispersed particles form explosive mixtures in air.
How is nitroaniline obtained from nitrobenzene?
Dissolve 6.7g (0.04 mol) of m-dinitrobenzene in 50 ml of hot methanol in a 250-ml round-bottomed flask and add, with shaking, the previously prepared methanolic solution of sodium hydrogen sulphide. Attach a reflux condenser and boil the mixture for 20 min; ignore any further sodium carbonate which may precipitate.

How is meta nitroaniline prepared from nitrobenzene?
Add 101 g (55 ml) of concentrated sulphuric acid cautiously to 75 ml of water contained in a 1-litre beaker and introduce 35 g (0.25 mol) of finely powdered m-nitroaniline. Add 100-150g of finely crushed ice and stir until the m-nitroaniline has been converted into the sulphate and a homogeneous paste results.
