**Question: What is the IUPAC name of this compound?** **Compound Structure:** CH2CH3 | CH3—CH—CH—CH2CH2CH3 | CH3 **Multiple Choice Answers:** 1. 2-methyl-3-ethylhexane 2. 4-ethyl-5-methylheptane (Selected Option) 3. 3-ethyl-2-methylhexane **Explanation of Compound Naming:** To determine the correct IUPAC name of an organic compound, you need to follow these steps: 1. **Identify the longest continuous carbon chain:** This will serve as the base name of the compound. In this case, the longest chain has 7 carbons, indicating it belongs to the heptane series. 2. **Number the carbon atoms in the longest chain:** Start numbering from the end of the chain nearest to any substituent group. This ensures that substituent groups get the lowest possible numbers. 3. **Identify and name the substituents:** In this case, there is an ethyl group (CH2CH3) and a methyl group (CH3) attached to the chain. 4. **Assign numbers to the substituents:** Give the substituents numbers corresponding to the carbon atom to which they are attached. 5. **Compile the name:** Combine the substituents and the base name. Place substituents in alphabetical order with their corresponding numbers. In the given compound structure: - The longest continuous chain has 7 carbon atoms. - From the left, the ethyl group (CH2CH3) is on the fourth carbon and the methyl group (CH3) is on the fifth carbon. So, the correct IUPAC name for the compound is **4-ethyl-5-methylheptane**.
