Molecular formula `C_(4)H_(10)O` represent

Options

A. Two primary alcohol
B. One secondary alcohol
C. One tertiary alcohol
D. All of these

Explanation

To determine what the molecular formula \( C_4H_{10}O \) represents, we can follow these steps:

### Step 1: Analyze the Molecular Formula
The molecular formula \( C_4H_{10}O \) indicates that the compound contains:
- 4 Carbon (C) atoms
- 10 Hydrogen (H) atoms
- 1 Oxygen (O) atom

### Step 2: Determine the Degree of Alcohol
To identify the type of alcohol, we need to consider how the hydroxyl group (–OH) is attached to the carbon skeleton. The carbon atoms can be arranged in different ways, leading to different structural isomers.

### Step 3: Draw Possible Structures
1. **Structure 1**:
- A straight-chain alcohol:
- CH3-CH2-CH(OH)-CH3 (where the –OH is attached to a secondary carbon)

2. **Structure 2**:
- A branched-chain alcohol:
- CH3-CH(OH)-CH2-CH3 (where the –OH is also attached to a secondary carbon)

### Step 4: Identify the Type of Alcohol
In both structures, the hydroxyl group is attached to a carbon that is connected to two other carbons, making it a secondary alcohol.

### Step 5: Conclusion
Based on the analysis, the molecular formula \( C_4H_{10}O \) represents a secondary alcohol.

### Final Answer
The molecular formula \( C_4H_{10}O \) represents a secondary alcohol.
