2. Nitrobenzene - Wikipedia

   en.wikipedia.org/wiki/Nitrobenzene

   Nitrobenzene is an aromatic nitro compound and the simplest of the nitrobenzenes, with the chemical formula C 6 H 5 NO 2. It is a water-insoluble pale yellow oil with an almond -like odor. It freezes to give greenish-yellow crystals.

4. Pentachloronitrobenzene - Wikipedia

   en.wikipedia.org/wiki/Pentachloronitrobenzene

   PCNB is prepared by chlorination of nitrobenzene at 60–70 °C in chlorosulfuric acid, with iodine as a catalyst. It can also be produced by the nitration of chlorinated benzenes. A side product of the synthesis of PCNB is hexachlorobenzene (HCB), which is considered as hazardous as PCNB. [1] 5 Cl 2 + C 6 H 5 NO 2 → C 6 Cl 5 NO 2 + 5 HCl

   Boiling point 175 to 180 °C (347 to 356 °F; 448 to 453 K) (3 mmHg) Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

7. 4-Nitrobenzaldehyde - Wikipedia

   en.wikipedia.org/wiki/4-Nitrobenzaldehyde

   4-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO.It is one of three isomers of nitrobenzaldehyde. It contains a nitro group para-substituted to an aldehyde.

8. 1,3-Dinitrobenzene - Wikipedia

   en.wikipedia.org/wiki/1,3-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.
