Ethane is a hydrocarbon molecule with a structural formula consisting of two carbon atoms bonded by a single bond (C-C) and six hydrogen atoms bonded to those carbon atoms. The Lewis representation of ethane shows that each carbon atom has three bonds, with hydrogen atoms filling in the remaining bonding positions. Regarding its structural characteristics, ethane is a nonpolar molecule because the electronegativity difference between carbon and hydrogen atoms is relatively small, leading to equal sharing of electrons within the carbon-hydrogen bonds. The Lewis formula of ethane, C2H6, contributes to its chemical properties, such as its low boiling point and high flammability.
