Both methane (CH₄) and butane (C₄H₁₀) are organic compounds that share certain similarities in their composition. To understand what they have in common, let's analyze the molecular formulas:
1. Methane (CH₄):
- Consists of one carbon atom (C).
- Consists of four hydrogen atoms (H).
2. Butane (C₄H₁₀):
- Consists of four carbon atoms (C).
- Consists of ten hydrogen atoms (H).
When we compare these two compounds, we observe that:
- Both compounds have carbon atoms.
- Both compounds have hydrogen atoms.
The statements given are:
1. They contain both carbon and hydrogen.
2. They contain only carbon.
3. They contain only hydrogen.
From our analysis, we can see that both methane and butane contain both carbon and hydrogen atoms. Therefore, the correct statement is:
They contain both carbon and hydrogen.
This is what these organic compounds have in common.
