Why the meta-dinitrobenzene acts as an electrophile?
It is an electrophilic aromatic substitution reaction 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 concentrated sulphuric acid.
What is the formula for 1 3 dinitrobenzene?
1,3-Dinitrobenzene is an organic compound with the formula C 6 H 4 (NO 2) 2. It is one of three isomers of dinitrobenzene. The compound is a yellow solid that is soluble in organic solvents. 1,3-Dinitrobenzene is accessible by nitration of nitrobenzene.
What are the isomers of dinitrobenzenes?
Dinitrobenzenes are chemical compounds composed of a benzene ring and two nitro group (-NO 2) substituents. The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene.
What is 1-3-dinitrobenzene?
It is one of three isomers of dinitrobenzene. The compound is a yellow solid that is soluble in organic solvents. 1,3-Dinitrobenzene is accessible by nitration of nitrobenzene. The reaction proceeds under acid catalysis using sulfuric acid.
What is the standard state of dinitrobenzene at 25 degrees Celsius?
