42 Lewis Structures Problems Chemistry LibreTextsEthane is a hydrocarbon molecule with a structural formula consisting of two carbon atoms bonded by a single bond (carbon-carbon bond) and six hydrogen atoms bonded to those carbon atoms. The structural representation of ethane shows that each carbon atom has three valence 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 physical properties, such as its comparatively low boiling point and high flammability.
