Questions & Step-by-Step Solutions
What is the IUPAC name of the compound with the structure CH3-CH(CH3)-C(=O)-OH?
Step 1: Identify the longest carbon chain in the compound. The structure CH3-CH(CH3)-C(=O)-OH has a chain of 4 carbon atoms.
Step 2: Determine the functional group. The -C(=O)-OH part indicates that this is a carboxylic acid.
Step 3: Number the carbon chain starting from the end closest to the carboxylic acid group. This gives us the following numbering: 1 (C=O-OH), 2 (CH), 3 (CH3), 4 (CH3).
Step 4: Identify any substituents. There is a methyl group (CH3) on the second carbon.
Step 5: Combine the information. The longest chain has 4 carbons (butanoic acid) and there is a methyl group on the second carbon, making it 2-methylbutanoic acid.
