Disubstituted Benzenes: The Strongest Electron-Donor “Wins”
2018年3月19日 · The major product for nitration of m-nitrotoluene is 3,4-dinitrotoluene, consistent with the strongest donor (ortho-para directing methyl) “winning” over the (meta-directing) nitro group. Note that nitration of 2,4- or 2,6-nitrotoluene leads to the common explosive 2,4,6-trinitrotoluene (TNT)!
Nitrobenzene - Wikipedia
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.
CHAPTER 4 CHEMICAL AND PHYSICAL INFORMATION - National …
Nitrobenzene is a colorless to pale yellow oily liquid composed of a benzene ring with a single substituted nitro group. The compound is a synthetic chemical, and it does not occur naturally. It has an odor similar to bitter almonds or shoe polish.

organic chemistry - What is the numbering of substituted benzene ...
2016年6月11日 · Halides and nitro groups aren't considered to be functional groups in nomenclature, they are substituents, while a hydroxy group is a functional group e.g. you would never say phenyl chloride or hydroxybenzene, while chlorobenzene and benzenol (phenol) are preferred names. Understand the difference?

Nitrobenzenes - Wikipedia
Nitrobenzenes are a group of nitro compounds consisting of one or more nitro groups as substituents on a benzene core. They have the formula C 6 H 6–n (NO 2) n, where n = 1–6 is the number of nitro groups. Depending on the number of nitro groups, there may be several constitutional isomers possible.
