2. o-nitrobenzoic acid

Step-by-step solution

IUPAC nomenclature

It is a method to give a scientific name to the organic compounds recommended by the Indian Union of Pure and Applied Chemistry.

Nomenclature of benzene

IUPAC rules used for naming of benzene

1. Name the parent aromatic benzene ring
2. Assign numbering to the substituents
3. Assign the first number to the bulky group
4. Halogens get the priority
5. Write the name of the molecule in alphabetic

To identify the IUPAC from the structure of compound A

1. The parent ring is a benzene ring attached with OH so phenol
2. Isopropyl is present at the meta position to the OH group
3. So, IUPAC's name is m-isopropyl phenol
4. So, the structure must be:

To identify the IUPAC from the structure of compound B

1. The parent ring is a benzene ring attached with COOH which is acid so benzoic acid
2. The Nitro group is present at the ortho position to the COOH group
3. So, IUPAC name is o-nitro benzoic acid
4. So, the structure must be:
