Answer:
Butane
Step-by-step explanation:
Butane is an alkane.
The general formula for an alkane is CₙH₂ₙ₊₂.
Butane has four carbon toms, so its formula is C₄H₁₀.
Propane is wrong. It has three carbon atoms, so its formula is C₃H₈.
Butene is wrong. The general formula for an alkene is CₙH₂ₙ, so the formula is C₄H₈.
Propene is wrong. It has three carbon atoms, so its formula is C₃H₆.
