What is the correct relationship between the following compounds?
`CH_(3)-CH_(2)-undersetunderset(CH_(3))(|)(CH)-CH_(2)-CH_(3),CH_(3)-CH_(2)-CH_(2)-CH_(2)-undersetunderset(CH_(3))(|)(CH_(2))`

Options

A. Chain isomers
B. Position isomers
C. Functional isomers
D. Identical

Explanation

To determine the correct relationship between the two given compounds, we will follow these steps:

### Step 1: Identify the Molecular Formula
First, we need to find the molecular formula of both compounds.

- **Compound 1**: `CH₃-CH₂-(CH₃)(CH)-CH₂-CH₃`
- Count the carbon (C) and hydrogen (H) atoms:
- C: 6 (from the structure)
- H: 14 (from the structure)
- Therefore, the molecular formula is C₆H₁₄.

- **Compound 2**: `CH₃-CH₂-CH₂-CH₂-(CH₃)(CH₂)`
- Count the carbon (C) and hydrogen (H) atoms:
- C: 6 (from the structure)
- H: 14 (from the structure)
- Therefore, the molecular formula is C₆H₁₄.

### Step 2: Analyze the Structure
Next, we analyze the structure of both compounds to determine their main carbon chains.

- **Compound 1** has a main chain of 5 carbon atoms with a branching (substituent) from the second carbon.
- **Compound 2** has a straight chain of 6 carbon atoms.

### Step 3: Determine the Type of Isomerism
Since both compounds have the same molecular formula (C₆H₁₄) but different structures, they exhibit isomerism.

- The difference in the arrangement of carbon atoms indicates that they are **chain isomers**. This is because one compound has a branched structure while the other has a straight chain.

### Step 4: Conclusion
The correct relationship between the two compounds is that they are **chain isomers** of each other.

### Summary
- Both compounds have the same molecular formula (C₆H₁₄).
- They differ in the arrangement of their carbon skeletons.
- Therefore, they are classified as chain isomers.
