C2H6 is a hydrocarbon molecule with a Lewis consisting of two carbon atoms bonded by a single bond (carbon-carbon bond) 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 valencies. Regarding its chemical properties, 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 structure of ethane, C2H6, contributes to its chemical features, such as its low boiling point and relatively high flammability.
