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. its chemical 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 C-H
bonds. The structural structure of ethane, C2H6, contributes to its physical features, such as its comparatively low boiling point and relatively high flammability.
