Themajor constituent of natural gas is

Options

A. methane
B. propane
C. butane
D. hexane.

Answer

To determine the major constituent of natural gas, we can follow these steps:

### Step 1: Understand what natural gas is
Natural gas is a naturally occurring gas that is primarily composed of hydrocarbons. It is found deep beneath the earth's surface and is often associated with other fossil fuels.

**Hint:** Natural gas is a mixture of different hydrocarbons, primarily found underground.

### Step 2: Identify the components of natural gas
Natural gas contains various hydrocarbons, including:
- Methane (CH₄)
- Ethane (C₂H₆)
- Propane (C₃H₈)
- Butane (C₄H₁₀)
- Pentane (C₅H₁₂)
- Hexane (C₆H₁₄)

**Hint:** Look for the common hydrocarbons that are typically found in natural gas.

### Step 3: Determine the major constituent
Among these hydrocarbons, methane is the most abundant component. It constitutes about 70% to 90% of natural gas.

**Hint:** Focus on which hydrocarbon is present in the highest percentage in natural gas.

### Step 4: Acknowledge other minor components
In addition to methane, natural gas may contain small amounts of other gases such as carbon dioxide (CO₂), nitrogen (N₂), and water vapor.

**Hint:** Remember that while there are other components, they are present in much smaller quantities compared to methane.

### Conclusion
The major constituent of natural gas is methane (CH₄).

**Final Answer:** Methane is the major constituent of natural gas.
