The chemical formula for propane is \( \text{C}_3\text{H}_{8} \). This formula provides important information about the composition and structure of propane as a molecule.
1. **Carbon Atoms (\( \text{C} \))**: The "3" in \( \text{C}_3 \) indicates that propane contains three carbon atoms. In organic chemistry, carbon is a fundamental building block for many compounds, and its ability to form stable bonds with other carbon atoms is a key characteristic of organic molecules.
2. **Hydrogen Atoms (\( \text{H} \))**: The "8" in \( \text{H}_8 \) signifies that there are eight hydrogen atoms in propane. Each carbon atom typically forms four bonds, and in hydrocarbons like propane, these bonds are usually with hydrogen atoms.
3. **Structural Implications**: The molecular formula \( \text{C}_3\text{H}_8 \) suggests that propane is an alkane, which is a saturated hydrocarbon meaning it contains only single bonds between carbon atoms. In propane, the structure can be visualized as a straight-chain of three carbon atoms, where the carbon atoms are bonded to enough hydrogen atoms to fulfill the tetravalency of carbon.
4. **General Alkane Formula**: Propane follows the general formula for alkanes, which is \( \text{C}_n\text{H}_{2n+2} \). For propane, when \( n = 3 \), substituting into the formula gives \( 2(3) + 2 = 8 \), confirming that the formula \( \text{C}_3\text{H}_{8} \) is consistent with the expected number of hydrogen atoms for three carbon atoms.
In summary, the chemical formula \( \text{C}_3\text{H}_{8} \) for propane indicates that it consists of three carbon atoms and eight hydrogen atoms, characteristic of a saturated alkane.
