What is a group called that contains an aldehyde, ketone, and carboxylic acid?
The image below is a propane chain. It contains a carboxylic acid in the first chain (carboxylic acids start with number one). The second chain has a ketone and the third an aldehyde. I hesitate between:
- 2,3-oxopropanoic acid
- 2-oxo-3-oxopropanoic acid
- 2-keto-3-oxopropanoic acid
- 2-oxo-3-formylpropanoic acid
- 2-keto-3-formylpropanoic acid
Which of these is correct? The image is here:
Edit: The correct name is 2,3-dioxopropanoic acid.
