What is the chemical formula for butane?

C3H8
H2SO4
CH4
C4H10

The correct answer is: C4H10

The chemical formula for butane is indeed represented as C4H10. Butane is an alkane, a type of hydrocarbon that consists exclusively of carbon (C) and hydrogen (H) atoms. In its molecular structure, butane has four carbon atoms and ten hydrogen atoms, which perfectly corresponds to the formula C4H10. In contrast, the other choices represent different compounds: C3H8 is propane, H2SO4 is sulfuric acid, and CH4 is methane. Each of these compounds has its own unique structure and properties, distinguishing them from butane, which is significant in the context of organic chemistry and fuels.
