What is the molecular formula of butane?

Correct option is D

The correct answer is (d) C₄H₁₀.
· Butane is an alkane with the molecular formula C₄H₁₀, consisting of four carbon atoms and ten hydrogen atoms.
· It is a colorless, flammable gas at room temperature and is used as a fuel in lighters and portable stoves.
· Butane can exist in two structural forms, n-butane and isobutane (branched-chain isomer), which have slightly different properties but the same molecular formula.
Additional Knowledge:
· C₅H₁₂ - This is the molecular formula for pentane, an alkane with five carbon atoms.
· C₂H₆ - This is the molecular formula for ethane, a simpler alkane with two carbon atoms.
· C₅H₈ - This formula represents an alkyne like pentyne, with a triple bond between carbon atoms, not butane.
