The formula of Ethane is

Correct option is B

Ethane is a saturated hydrocarbon (alkane) with the molecular formula C₂H₆, meaning it contains two carbon atoms and six hydrogen atoms. It is structurally represented as CH₃–CH₃. Ethane is a colorless, odorless gas used in the petrochemical industry to produce ethylene through cracking. It burns cleanly and is found in natural gas. Option (a) is methane (CH₄), the simplest alkane; option (c) is propane (C₃H₈), and option (d) is butane (C₄H₁₀). Ethane plays a key role in organic chemistry and industrial fuel systems.
