Questions & Step-by-Step Solutions

Which of the following is the correct IUPAC name for CH3CH2CH2OH?
  • Step 1: Identify the structure of the molecule CH3CH2CH2OH. This molecule has a chain of carbon atoms and a hydroxyl group (OH).
  • Step 2: Count the number of carbon atoms in the chain. There are four carbon atoms (C).
  • Step 3: Determine the longest continuous chain of carbon atoms. The longest chain is four carbons long, which is called 'butane'.
  • Step 4: Identify the position of the hydroxyl group (OH). In this case, the OH group is attached to the first carbon in the chain.
  • Step 5: Combine the information from the previous steps. Since there are four carbons and the OH group is on the first carbon, the IUPAC name is 'Butan-1-ol'.
