Questions & Step-by-Step Solutions

What is the IUPAC name for the compound with the structure CH3-CH2-CH2-CH2-CH=CH2?
  • Step 1: Identify the longest continuous chain of carbon atoms in the structure. In this case, there are 6 carbon atoms in a row.
  • Step 2: Count the number of carbon atoms. There are 6 carbon atoms, which means the base name will be 'hexane'.
  • Step 3: Identify the presence of a double bond in the structure. The double bond is located between the first and second carbon atoms.
  • Step 4: Since there is a double bond, we change 'hexane' to 'hexene'.
  • Step 5: Number the carbon chain starting from the end closest to the double bond. The double bond starts at carbon 1.
  • Step 6: Combine the information: The compound is named '1-Hexene' because the double bond starts at the first carbon.
