Question

There are several aromatic compounds with the formula C8H9Cl. Draw those that have a trisubstituted ring where the methyl groups are oriented ortho.

Answer 1

`3-Chloro-1,2-dimethylbenzene`

`4-Chloro-1,2-dimethylbenzene`

Step-by-step explanation:

Such types of compounds in which conjugated planer ring system and delocalized pi electrons are present are called aromatic compounds such as Toluene, Benzene and some other. Generally, these compounds follow Huckle's rule. The trisubstituted ring means a compound in which three hydrogen atoms are replaced by three other groups. In the given compound two hydrogen atoms are replaced by two methyl groups and one hydrogen atom is replaced by one Chlorine atom. From the given compound
`3-Chloro-1,2-dimethylbenzene`, and
`4-Chloro-1,2-dimethylbenzene` can be drawn.
