Q: What is the IUPAC name of the compound CH2=CH-CH2-CH3?
Solution: The compound CH2=CH-CH2-CH3 is named 1-Butene as the double bond is between the first and second carbon.
Steps: 6
Step 1: Identify the longest continuous chain of carbon atoms in the compound. In CH2=CH-CH2-CH3, there are 4 carbon atoms in a row.
Step 2: Count the number of carbon atoms. There are 4 carbon atoms, which means the base name is 'butane'.
Step 3: Determine the presence of a double bond. The 'CH2=CH' part indicates there is a double bond between the first and second carbon atoms.
Step 4: Since there is a double bond, we change 'butane' to 'butene'.
Step 5: Number the carbon chain starting from the end closest to the double bond. The double bond is between the first and second carbon, so we label it as '1-butene'.
Step 6: Combine the information to get the final IUPAC name: '1-Butene'.
