Nitration of nitrobenzene at 125oC with mixed acids gives:
Nitration of nitrobenzene at 125oC with mixed acids gives:
The correct option is A meta-dinitrobenzene
1,3-Dinitrobenzene is accessible
by nitration of nitrobenzene. The reaction proceeds under acid catalysis using
sulfuric acid. The directing effect of the nitro group of nitrobenzene leads to
93% of the product resulting from nitration at the meta-position. The ortho-
and para-products occur in only 6% and 1%, respectively.
Dinitrobenzenes are chemical
compounds composed of a benzene ring and two nitro group (−NO2) substituent’s. The three possible arrangements
of the nitro groups afford three isomers, 1,2-dinitrobenzene,
1,3-dinitrobenzene, and 1,4-dinitrobenzene. Each isomer has the chemical
formula C6H4N2O4 and a molar mass of about 168.11 g/mol. 1,3-Dinitrobenzene is
the most common isomer and it is used in the manufacture of explosives.
