Which are the correct IUPAC names of the following compounds ?
`overset(H_3C-CH_2-CH_2-CH_2-underset(CH_3)underset|underset(H_3C-C-CH_3)underset|underset(CH_2)underset|"CH"-CH_2-CH_2-CH_2-CH_2-CH_3)`

Options

A. 5-(2'-2'-Dimethylpropyl)decane
B. 4-Butyl-2,2-dimethylnonane
C. 2,2-Dimethyl-4-pentyloctane
D. 5-Neopentyldecane

Explanation

To determine the correct IUPAC names of the given compounds, we will follow these steps:

### Step 1: Identify the Longest Carbon Chain
The first step in naming a hydrocarbon is to identify the longest continuous carbon chain in the structure. This chain will serve as the parent hydrocarbon.

### Step 2: Number the Carbon Chain
Once the longest chain is identified, we need to number the carbon atoms in the chain. The numbering should be done in such a way that the substituents (branches) get the lowest possible numbers.

### Step 3: Identify and Name Substituents
Next, we identify any substituents attached to the main carbon chain. Common substituents include alkyl groups such as methyl (−CH₃), ethyl (−C₂H₅), propyl (−C₃H₇), etc. We also need to determine the position of each substituent on the carbon chain.

### Step 4: Combine the Names
After identifying the longest chain and the substituents, we combine the names. The substituents are listed in alphabetical order, and their positions are indicated by the numbers assigned during the numbering of the carbon chain. If there are multiple identical substituents, we use prefixes like di-, tri-, etc.

### Step 5: Finalize the IUPAC Name
Finally, we write the complete IUPAC name by placing the substituents before the parent name, ensuring to follow the correct order and punctuation.

### Example Application
1. **Identify the Longest Carbon Chain**: In the given compound, the longest chain has 10 carbon atoms, making it a decane.
2. **Number the Carbon Chain**: Number the chain from one end to the other, ensuring that substituents receive the lowest possible numbers.
3. **Identify and Name Substituents**: There are two substituents: a neopentyl group and dimethyl groups.
4. **Combine the Names**: The substituents are named according to their positions and combined with the parent name.
5. **Finalize the IUPAC Name**: The final IUPAC name is 5-neopentyl-2,2-dimethyldecane.

### Conclusion
The correct IUPAC names for the compounds are:
1. 5-neopentyl-2,2-dimethyldecane
2. 5-neopentyldecane
