Questions & Step-by-Step Solutions

What is the IUPAC name for the compound with the structure CH3-CH2-CH(CH3)-OH?
  • Step 1: Identify the longest continuous chain of carbon atoms in the structure CH3-CH2-CH(CH3)-OH.
  • Step 2: Count the number of carbon atoms in the longest chain. There are four carbon atoms.
  • Step 3: Determine the position of the hydroxyl group (-OH) on the carbon chain. The -OH group is attached to the second carbon.
  • Step 4: Name the longest chain based on the number of carbon atoms. A four-carbon chain is called 'butane.'
  • Step 5: Since the -OH group is on the second carbon, we add '2-' before 'butanol' to indicate its position.
  • Step 6: Combine the information to get the full IUPAC name: 2-Butanol.
