Questions & Step-by-Step Solutions

What is the IUPAC name for the compound with the formula C4H8O?
  • Step 1: Identify the molecular formula C4H8O. This means the compound has 4 carbon atoms, 8 hydrogen atoms, and 1 oxygen atom.
  • Step 2: Determine the possible structures for C4H8O. It can be an alcohol, ether, or ketone.
  • Step 3: Since there is an -OH group (hydroxyl group) in the structure, we can classify it as an alcohol.
  • Step 4: Count the carbon atoms in the longest chain. The longest chain has 4 carbon atoms, which gives us 'butan' as the base name.
  • Step 5: Identify the position of the -OH group. In butan-2-ol, the -OH group is on the second carbon.
  • Step 6: Combine the base name and the position of the -OH group to get the IUPAC name: butan-2-ol.
