`C_(4)H_(10)` (hydrocarbon) is the main constituent of

Options

A. LPG
B. natural gas
C. petroleum
D. coal gas

Answer

To determine what `C_(4)H_(10)` (butane) is the main constituent of, we can follow these steps:

### Step 1: Identify the compound
The chemical formula `C_(4)H_(10)` represents a hydrocarbon known as butane.

### Step 2: Understand the options given
The options provided are:
- A) LPG (Liquefied Petroleum Gas)
- B) Natural gas
- C) Petroleum
- D) Coal gas

### Step 3: Analyze the constituents of each option
- **LPG (Liquefied Petroleum Gas)**: LPG is primarily composed of propane and butane. Therefore, butane is indeed a main constituent of LPG.
- **Natural gas**: This is primarily composed of methane (C₁H₄) and does not contain butane as a major component.
- **Petroleum**: While petroleum is a complex mixture of hydrocarbons, it does not specifically highlight butane as a main constituent.
- **Coal gas**: This is a mixture of gases produced from coal, primarily consisting of hydrogen, methane, and carbon monoxide, and does not include butane as a significant component.

### Step 4: Conclusion
Since butane is a major component of LPG, the correct answer is **A) LPG**.

### Final Answer:
C_(4)H_(10) (butane) is the main constituent of **LPG (Liquefied Petroleum Gas)**.
