Question

Name the following aromatic hydrocarbon:

CH,CH;
CH,CH3
A. 1,4-dimethylbenzene
B. 1,4-dihexylbenzene
C. 2,6-diethylbenzene
D. 1,4-diethylbenzene

Answer 1

A. 1,4-dimethylbenzene

Step-by-step explanation:

The compound CH,CH;CH,CH3 is a benzene derivative with two methyl groups attached to the benzene ring. The positions of the methyl groups on the ring are indicated by the numbers 1 and 4, which correspond to the carbon atoms at the end of the two double bonds in the benzene ring. This compound is therefore 1,4-dimethylbenzene. The other options listed are not correct because they contain the wrong number or type of substituents on the benzene ring.
