Questions & Step-by-Step Solutions
Which of the following is the correct IUPAC name for the compound CH3-CH2-CH2-CH2-COOH?
Step 1: Identify the structure of the compound. The formula CH3-CH2-CH2-CH2-COOH shows a chain of carbon atoms ending with a carboxylic acid group (COOH).
Step 2: Count the number of carbon atoms in the chain. There are 5 carbon atoms (4 from CH3-CH2-CH2-CH2 and 1 from COOH).
Step 3: Determine the type of compound. Since the compound has a carboxylic acid group (COOH), it is classified as a carboxylic acid.
Step 4: Use the IUPAC naming rules. For a carboxylic acid with 5 carbon atoms, the name is derived from 'pentane' (the alkane with 5 carbons) and changes to 'pentanoic acid'.
Step 5: Conclude that the correct IUPAC name for the compound CH3-CH2-CH2-CH2-COOH is Pentanoic acid.
