Questions & Step-by-Step Solutions

What is the correct IUPAC name for the compound with the structure CH3-CH(CH3)-CH2-COOH?
  • Step 1: Identify the longest carbon chain in the compound. Count the number of carbon atoms in the chain.
  • Step 2: The longest chain has 4 carbon atoms, which is called butanoic acid.
  • Step 3: Look for any branches (methyl groups) attached to the main chain. In this case, there is a methyl group (CH3) on the second carbon.
  • Step 4: Since the methyl group is on the second carbon, we name it 2-Methyl.
  • Step 5: Combine the branch name with the main chain name. The full name is 2-Methylbutanoic acid.
