What is the IUPAC name for the compound with the formula C3H7-COOH?

Step 1: Identify the functional group in the compound. The formula C3H7-COOH indicates that it has a carboxylic acid group (-COOH).
Step 2: Count the number of carbon atoms in the main chain. The 'C3H7' part indicates there are 3 carbon atoms in the main chain.
Step 3: Determine the structure of the carbon chain. The three carbon atoms can be arranged in a straight chain or a branched chain.
Step 4: Recognize that the compound is a branched-chain carboxylic acid. The structure shows that one carbon is attached to the carboxylic acid group, and the other two are branched off.
Step 5: Name the compound according to IUPAC rules. The name for a 3-carbon carboxylic acid is 'propanoic acid', but since it is branched, it is called 'isobutyric acid'.
Step 6: Conclude that the IUPAC name for the compound C3H7-COOH is isobutyric acid.
