**Title: Understanding IUPAC Nomenclature for Organic Compounds** **Objective:** To determine the IUPAC name for the given chemical compound. **Chemical Structure:** The diagram presents a structural formula of an organic compound with the following elements: 1. A carbon-carbon double bond is denoted by "C=C". 2. A hydrogen atom (H) is bonded to the first carbon. 3. A bromine atom (Br) is bonded to the first carbon. 4. A chlorine atom (Cl) is referenced in the question for naming but not shown connected in the image. 5. An ethyl group (CH₂CH₂CH₃) is attached to the second carbon. **Explanation:** The structure shown is a monosubstituted alkene with a bromine atom and an ethyl group attached to the carbon atoms involved in a double bond. **Steps to Determine the IUPAC Name:** 1. **Identify the Longest Carbon Chain:** - The longest chain that contains the double bond has two carbon atoms; hence, it is an ethene base. 2. **Number the Carbon Atoms:** - Number the carbon atoms in the main chain starting from the end nearest a substituent. The double bond should get the lowest possible number. 3. **Identify and Name the Substituents:** - At the first carbon (C-1), there is a bromine atom, and on C-2, there is an ethyl group. 4. **Combine the Components into the Compound Name:** - The compound name is based on substituents and their positions. Since bromine is not explicitly prioritized over chlorine in the structure provided (i.e., based on alphabetical order without further information where Cl should be), assume only the visible substituents are to be named: The compound can be named: - 1-Bromo-2-chloropropene if chlorine is assumed as being part of the structure, replacing the CH₂ component in the question. - 1-Bromo-1-propene if chlorine is not connected as shown. **Conclusion:** This provides an understanding of how to approach determining the IUPAC nomenclature, examining structural elements and naming conventions for clarity in organic chemistry education. **Note:** The relevant placement of chlorine should be clarified in practice for accurate naming.
