Find the IUPAC name of the compound.

The given compound is a substituted benzoic acid. We need to identify the positions of the substituents and name the compound according to the IUPAC rules. - The parent structure is benzoic acid, with a carboxyl group (-COOH) at position
1. - The other substituents are: - A bromine (Br) group attached at position
2. - A nitro (NO\(_2\)) group attached at position 3. Thus, the correct IUPAC name for this compound is 2-Bromo-3-nitrobenzoic acid.
Designate whether each of the following compounds is aromatic or not aromatic.
