Ethane 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 diagram of ethane shows that each carbon atom has three bonds, with hydrogen atoms filling in the remaining valencies. In terms of 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 💗 of ethane, C2H6, contributes to its chemical properties, such as its comparatively low boiling point and high flammability.
