Q
Q: Which of the following is the correct IUPAC name for the compound with the structure CH3-CH(CH3)-C(=O)-OH?
Solution: The compound has a carboxylic acid functional group and a methyl group on the third carbon of a four-carbon chain, making it 3-Methylbutanoic acid.
Steps: 6
Step 1: Identify the longest carbon chain in the compound. The longest chain has four carbon atoms, which is called butane.
Step 2: Determine the functional group present. The structure has a carboxylic acid group (-COOH), which indicates that it is a carboxylic acid.
Step 3: Number the carbon chain starting from the end closest to the carboxylic acid group. This gives the carboxylic acid carbon the lowest number (1).
Step 4: Identify the position of the methyl group (CH3) on the carbon chain. The methyl group is on the third carbon.
Step 5: Combine the information to name the compound. The name is formed by stating the position of the methyl group (3-) followed by the name of the acid (butanoic acid).
Step 6: The final IUPAC name is 3-Methylbutanoic acid.
