• B. 1-hydroxypent-2-en-1, 4-dione
• C. 4-oxopent-2-enoic acid
• D. 4-oxopentanoic acid

Answer 1

Answer:

C. 4-oxopent-2-enoic acid

The IUPAC name of CH₃COCH=CHCOOH is indeed:

4-Oxopent-2-enoic acid

Here's the breakdown:

• "4-Oxo-" indicates the presence of a ketone group at the 4th carbon.

• "Pent-" indicates a 5-carbon chain.

• "-2-enoic" indicates an alkene group at the 2nd carbon and a carboxylic acid group at the end.

IUPAC naming can be complex, but you nailed it!
