Q
Q: What is the correct IUPAC name for the compound with the structure CH3-CH(CH3)-C(=O)-OH?
Solution: The compound is 2-methylbutanoic acid, as the carboxylic acid is on the second carbon of the butane chain.
Steps: 5
Step 1: Identify the longest carbon chain in the compound. In this case, the longest chain has 4 carbon atoms, which is called butane.
Step 2: Look for the functional group present in the compound. Here, we have a carboxylic acid group (-COOH) attached to one of the carbon atoms.
Step 3: Determine the position of the carboxylic acid group. It is attached to the second carbon of the butane chain, making it a butanoic acid.
Step 4: Identify any substituents on the carbon chain. There is a methyl group (-CH3) attached to the second carbon, which makes it 2-methyl.
Step 5: Combine the information from the previous steps. The compound is named by combining the substituent and the main chain name, resulting in 2-methylbutanoic acid.
