How many benzenoid aromatic structures are possible in C7H7Cl?

Answer 1

In C7H7Cl, there are several possible benzenoid aromatic structures, primarily due to the different positions where the chlorine atom can be attached to the benzene ring. The compound can exist as a chlorinated toluene isomer, where the chlorine can be positioned ortho, meta, or para to the methyl group. This results in three distinct isomers: ortho-chlorotoluene, meta-chlorotoluene, and para-chlorotoluene. Therefore, the primary benzenoid aromatic structures possible in C7H7Cl are three.
