  2. Xylene - Wikipedia

    en.wikipedia.org/wiki/Xylene

    In organic chemistry, xylene or xylol (from Greek ξύλον (xylon) 'wood'; [1] [2] IUPAC name: dimethylbenzene) are any of three organic compounds with the formula (CH 3) 2 C 6 H 4. They are derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring; which hydrogens are substituted determines which of three ...

  3. o-Xylene - Wikipedia

    en.wikipedia.org/wiki/O-Xylene

    o-Xylene (ortho-xylene) is an aromatic hydrocarbon with the formula C 6 H 4 (CH 3) 2, with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m-xylene and p-xylene, the mixture being called xylene or xylenes. o-Xylene is a colourless slightly oily flammable ...

  4. p-Xylene - Wikipedia

    en.wikipedia.org/wiki/P-Xylene

    The p-stands for para-, indicating that the two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and m-xylene. All have the same chemical formula C 6 H 4 (CH 3) 2. All ...

  5. m-Xylene - Wikipedia

    en.wikipedia.org/wiki/M-Xylene

    The m-stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and p-xylene. All have the same chemical formula C 6 H 4 (CH 3) 2. All xylene isomers are ...

  6. C2-Benzenes - Wikipedia

    en.wikipedia.org/wiki/C2-Benzenes

    The C 2 benzenes are a class of organic aromatic compounds which contain a benzene ring and two other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers. There are three xylenes and one ethylbenzene .

  7. Dinitrobenzene - Wikipedia

    en.wikipedia.org/wiki/Dinitrobenzene

    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 C 6 H 4 N 2 O 4 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.

  8. Dihydroxybenzenes - Wikipedia

    en.wikipedia.org/wiki/Dihydroxybenzenes

    All three isomers have the chemical formula C 6 H 6 O 2. Similar to other phenols, the hydroxyl groups on the aromatic ring of a benzenediol are weakly acidic . Each benzenediol can lose an H + from one of the hydroxyls to form a type of phenolate ion.

  9. 1,2,4-Trimethylbenzene - Wikipedia

    en.wikipedia.org/wiki/1,2,4-Trimethylbenzene

    1,2,4-Trimethylbenzene, also known as pseudocumene, is an organic compound with the chemical formula C 6 H 3 (CH 3) 3. Classified as an aromatic hydrocarbon, it is a flammable colorless liquid with a strong odor. It is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar and petroleum (about 3%).
