C2H6 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 diagram of ethane shows that each carbon atom has three bonds, with hydrogen atoms filling in the remaining valencies. In terms of its structural 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 C-H bonds. The Lewis structure of ethane, C2H6, contributes to its chemical features, such as its comparatively low boiling point and high flammability.
