Let's break down the structure step-by-step to determine the correct IUPAC name for the given compound.
The structure is:
```
CH3
|
CH3-CH2-CH2-CH2-CH2-CH3
```
1. Identify the longest continuous carbon chain:
- The longest continuous carbon chain in this structure is 7 carbons long.
2. Name the parent hydrocarbon:
- For a chain of 7 carbons, the corresponding alkane name is "heptane".
3. Identify and name substituents:
- In this structure, no substituents like branches or additional groups are present that are different from the main chain (just the hydrogen atoms are implicit here).
Given this analysis, the correct IUPAC name for the compound, as it consists only of a straight chain of 7 carbons with no additional substituents, is:
- Heptane
Let's confirm this with the choices given again:
- 2-methylhexane: This would indicate a 6-carbon chain (hexane) with a methyl group attached to the second carbon, which is not the case here.
- 5-methylhexane: This would indicate a 6-carbon chain with a methyl group attached to the fifth carbon, which is again not the case.
- 2-methylpentane: This would be a 5-carbon chain (pentane) with a methyl group attached to the second carbon.
- heptane: This is what we have identified our compound as.
- methylhexane: This indicates a hexane chain with a single methyl substituent somewhere, which again is not the case.
Thus, the answer is:
- heptane
