What is the IUPAC name of a bromobenzene with carboxylic acid attached
LuckyWell [14K]

Answer:

Bromobenzoic acid  

Explanation:

COOH has higher priority than Br, so the parent name is benzoic acid.

The COOH group is automatically on C1 of the ring, and the other aromatic carbons are numbered sequentially around the ring.

The name of the substituent is joined to that of the parent, and the locant is attached to that with a hyphen.

The generic IUPAC name is bromobenzoic acid.

There are three isomers of benzoic acid — 2-bromobenzoic acid, 3-bromobenzoic acid, and 4-bromobenzoic acid —  so you must always specify which one you mean.
