### Question 10: Organic Chemistry Structure Naming #### Name the structure. **Image Description:** The image shows a chemical structure with the following groups attached to a central double bond: - A CH₃ (methyl) group is attached to the carbon on the left side of the double bond. - A CH₃ (methyl) group is also attached to the same carbon on the left side of the double bond. - A CH₃CH₂ (ethyl) group is attached to the right side of the double bond. - A CH₂CH₂CH₂OH (propanol) group is attached to the same carbon on the right side of the double bond. **Possible Answers:** 1. \( (E) \)-3,4-dimethyl-3-hepten-7-ol 2. \( (Z) \)-3,4-dimethyl-3-hepten-7-ol 3. \( (E) \)-4,5-dimethyl-4-heptenol 4. \( (Z) \)-4,5-dimethyl-4-hepten-1-ol 5. \( (E) \)-4,5-dimethyl-4-hepten-1-ol **Explanation of the Structure:** To correctly name this structure, we need to consider the following IUPAC (International Union of Pure and Applied Chemistry) naming rules: 1. Determine the longest carbon chain that includes the double bond and the hydroxyl group. 2. Number the carbon chain in such a way that the double bond and the hydroxyl group get the lowest possible locants (numbers). 3. Assign E/Z or cis/trans stereochemistry if applicable for the double bond. 4. Identify and name substituent groups attached to the main chain. 5. Combine all parts of the name in the order: stereochemistry, substituent positions and names, main chain name, position of double bond, and position of hydroxyl group. By following these steps, the correct name of the given structure can be determined.

### Question 11: **What is the IUPAC name for the following compound?** **Diagram:** The diagram represents a hexagonal ring structure with alternating double bonds, and each vertex of the hexagon has a chlorine atom (Cl) attached to it. **Options:** - ○ 1,2,3,4,5,5-hexachlorocyclohexa-1,3-diene - ○ 1,1,2,3,4,5-hexachlorocyclohexa-2,4-diene - ○ 1,2,3,4,5,6-methylcyclopentadiene - ○ 1,2,3,4,5-hexachlorocyclohexa-1,3-diene - ○ hexacyclohexadiene **Description of Diagram:** The molecule shown in the diagram is a cyclohexadiene with chlorine atoms attached to each carbon in the ring. - The ring contains six carbon atoms. - There are alternating double bonds between the carbons in positions 1,3 and 2,4. - Each carbon in the ring has a chlorine atom attached. **Explanation:** The correct IUPAC naming will specify the positions of the chlorine atoms and the positions of the double bonds in the cyclohexane ring. By analyzing the structure: - The positions 1,2,3,4,5,6 are fully substituted by chlorines. - The longest chain involved is a cyclohexa-diene. Given the options and the observed structure, the correct answer aligns with the given naming conventions in organic chemistry. **Answer:** - ○ 1,2,3,4,5,6-hexachlorocyclohexa-1,3-diene
