Question

Write IUPAC name of the compound above.

• A. 2-Amino-4-hydroxybenzoic acid
• B. 6-Amino-4-hydroxybenzoic acid
• C. 3-Amino-4-carboxyphenol
• D. 2-Carboxy-5-hydroxyaniline

Answer 1

The correct option is A 2-Amino-4-hydroxybenzoic acid

The carboxylic acid is the functional group and remaining $2$ becomes substituents $-COOH$ given first importance.

The numbering starts from $-COOH$ group followed by $-N{H}_2$ group at carbon number 2 and $-OH$ group at carbon number 4.

Thus the IUPAC name will be:

2-Amino-4-hydroxybenzoic acid.
