Question

Mention the IUPAC name for the given structure.

• A. benzene-1,2-dicarboxylic acid
• B. benzenedicarboxylic acid
• C. dibenzoic acid
• D. benzene-1,2-dioic acid

Answer 1

The correct option is A benzene-1,2-dicarboxylic acid

If two or more identical substituents are present, numbers are separated by commas. Names of identical substituents are not repeated instead prefixes such as di(for 2), tri(for 3), tetra(for 4), penta(for 5), hexa(for 6) etc. are used.
So, the correct IUPAC name is Benzene-1,2-dicarboxylic acid
