n-propyl alcohol and isopropyl alcohol are examples of

Options

A. chain isomerism
B. position isomerism
C. tautomerism
D. functional group isomerism.

Answer

To determine the type of isomerism exhibited by n-propyl alcohol and isopropyl alcohol, we can follow these steps:

### Step 1: Understand the Structures of n-Propyl Alcohol and Isopropyl Alcohol
- **n-Propyl Alcohol**: This compound has a straight-chain structure with three carbon atoms (C3H8O). The hydroxyl group (-OH) is attached to the terminal carbon (C1).
- **Isopropyl Alcohol**: This compound also has three carbon atoms but has a branched structure. The hydroxyl group (-OH) is attached to the second carbon (C2) of the chain.

### Step 2: Identify the Key Differences
- Both compounds have the same molecular formula (C3H8O) and the same number of carbon atoms.
- The key difference lies in the position of the hydroxyl group. In n-propyl alcohol, the -OH group is on the first carbon, while in isopropyl alcohol, it is on the second carbon.

### Step 3: Classify the Type of Isomerism
- Since the only difference between n-propyl alcohol and isopropyl alcohol is the position of the hydroxyl group, this indicates that they are **position isomers**.
- Position isomerism occurs when the functional group (in this case, the hydroxyl group) is located at different positions on the carbon chain.

### Conclusion
Thus, n-propyl alcohol and isopropyl alcohol are examples of **position isomerism**.

### Final Answer
**Option B: Position Isomerism**
