Transcribed Image Text:**Question:**
Name the following:
**Diagram:**
The diagram shows a structure of 4 carbon atoms in a chain with single bonds connecting them. There is one oxygen atom connected between the second and third carbon atoms in the chain. Each carbon atom is bonded to hydrogen atoms to complete their four bonds.
Carbon-1:
- Connected to 3 hydrogen atoms and Carbon-2.
Carbon-2:
- Connected to 2 hydrogen atoms, Carbon-1, Carbon-3, and one oxygen atom.
Carbon-3:
- Connected to 2 hydrogen atoms, Carbon-2, Carbon-4, and one oxygen atom.
Carbon-4:
- Connected to 3 hydrogen atoms and Carbon-3.
**Options:**
1. □ acetone
2. □ butyraldehyde
3. □ diethylketone
4. □ diethyl ether
5. □ none of these
**Visual Explanation:**
The image presents a molecular structure with the chemical notation for the given compound. The compound is being asked to be named by selecting one of the provided options.

Transcribed Image Text:### Determining the Correct IUPAC Name for a Given Compound
**Question:**
A student named a compound 2,2-diethylpentane. Although this name correctly represents the connectivity of the compound, it is not a valid IUPAC name. What is the correct IUPAC name of this compound?
**Options:**
- 3-ethyl-3-methylhexane
- 3-methyl-3-propylpentane
- 2-ethyl-2-propylbutane
- 4,4-diethylpentane
**Solution Explanation:**
**Step-by-Step Analysis:**
1. **Verify the Given Name:**
- The provided name is 2,2-diethylpentane. This indicates a five-carbon chain (pentane) with two ethyl groups attached to the second carbon.
2. **Identify the Longest Carbon Chain:**
- Rather than starting with pentane as the main chain, identify the longest continuous carbon chain which should have the highest number of carbons.
3. **Name the Compound Correctly:**
- Realize that naming should minimize the locant numbers for substituents and prioritize longer chains.
**Correct Option:**
- **3-ethyl-3-methylhexane:**
- In this option, the longest chain is hexane (6 carbons).
- There are substituents on the third carbon.
- Two different substituents, ethyl and methyl, are correctly identified.
This analysis shows the appropriate method for determining the accurate IUPAC name. The correct IUPAC name of the compound originally named 2,2-diethylpentane is **3-ethyl-3-methylhexane.**
