1,4-dimethylbenzene is called _.
Correct answer: B. Para-xylene
- A. Ortho-xylene
- B. Para-xylene
- C. Para-methyl toluene
- D. Meta-methyl toluene
Explanation
Xylene is any of three organic compounds with the formula (CH3)2C6H4. They are derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring. In ortho benzene, the two methyl substituents are bonded to adjacent carbon atoms of a benzene ring, i.e., carbon no. 1 and 2. In para-xylene, one methyl group is at position 1 and the other at position 4.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
