Find out relation between the following compounds:
`CH_(3)CH_(2)CH_(2)underset(COOH)underset(|)(CHCH_(3)) and CH_(3)CH_(2)underset(COOH)underset(|)(CHCH_(2)CH_(3))`

Answer

To find the relation between the given compounds, we will analyze their structures and identify their characteristics step by step.

### Step 1: Identify the Molecular Formula
The first step is to determine the molecular formula of each compound.

1. **For the first compound**:
- Structure: `CH₃CH₂CH₂C(COOH)(CHCH₃)`
- Count the carbon atoms (C): 5 (from the chain and the substituents)
- Count the hydrogen atoms (H): 11
- Therefore, the molecular formula is **C₅H₁₁COOH**.

2. **For the second compound**:
- Structure: `CH₃CH₂C(COOH)(CH₂CH₃)`
- Count the carbon atoms (C): 5 (from the chain and the substituents)
- Count the hydrogen atoms (H): 11
- Therefore, the molecular formula is also **C₅H₁₁COOH**.

### Step 2: Analyze the Position of the Functional Group
Next, we will analyze the position of the carboxylic acid group (COOH) in both compounds.

1. **In the first compound**: The COOH group is attached to the second carbon of the main carbon chain.
2. **In the second compound**: The COOH group is attached to the third carbon of the main carbon chain.

### Step 3: Determine the Type of Isomerism
Since both compounds have the same molecular formula (C₅H₁₁COOH) but differ in the position of the COOH group, they are classified as position isomers.

### Conclusion
The two compounds are **position isomers** of each other because they have the same molecular formula but differ in the position of the functional group (COOH) within the carbon chain.
