Questions & Step-by-Step Solutions

What is the IUPAC name of the compound with the structure CH3-CH(CH3)-CH2-CH3?
  • Step 1: Identify the structure of the compound. The structure is CH3-CH(CH3)-CH2-CH3.
  • Step 2: Count the number of carbon atoms in the longest continuous chain. There are 4 carbon atoms in a row.
  • Step 3: Name the longest chain. A chain with 4 carbon atoms is called butane.
  • Step 4: Look for any branches (substituents) on the main chain. There is a methyl group (CH3) attached to the second carbon.
  • Step 5: Combine the names. Since there is a methyl group on the second carbon of butane, the full name is 2-methylbutane.
