Questions & Step-by-Step Solutions
What is the IUPAC name for the compound with the structure CH3-CH2-CH2-CH2-COOH?
Correct Answer: Pentanoic acid
Step 1: Identify the longest continuous chain of carbon atoms in the structure. In this case, there are five carbon atoms in a row: CH3-CH2-CH2-CH2-COOH.
Step 2: Count the number of carbon atoms in the chain. There are 5 carbon atoms.
Step 3: Determine the functional group present in the compound. The -COOH group indicates that it is a carboxylic acid.
Step 4: Combine the number of carbon atoms with the functional group name. Since there are 5 carbon atoms, the name will start with 'pent-' for pentane.
Step 5: Add 'oic acid' to the name to indicate that it is a carboxylic acid. Therefore, the final name is 'Pentanoic acid'.
