What is the chemical formula for propane?

C3H8
H2SO4
CH4
C4H10

The correct answer is: C3H8

The chemical formula for propane is represented as C3H8, which indicates that each molecule of propane consists of three carbon atoms and eight hydrogen atoms. This hydrocarbon is a member of the alkane family, characterized by single bonds between carbon atoms and saturated with hydrogen. Propane is commonly used as a fuel source for heating and cooking. Understanding the structure of propane is crucial for recognizing its properties and applications. The presence of three carbon atoms allows for the characteristic branching and bonding of the alkane series, influencing the compound's boiling point, volatility, and combustion properties. The significance of having eight hydrogen atoms highlights the complete saturation of carbon bonds, which is a defining feature of alkanes. Comparing with the other options, H2SO4 represents sulfuric acid, which is not related to propane at all. CH4 is the formula for methane, a simpler alkane with one carbon atom. C4H10 is the formula for butane, which has four carbon atoms. Understanding these differences helps clarify why C3H8 is the accurate representation for propane.
