Ethane 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 diagram of ethane shows that each carbon atom has three valence 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 structural
formula of ethane, C2H6, contributes to its physical properties, such as its comparatively low boiling point and high flammability.
