Learn to determine if C4H10 (Butane) is polar or non-polar based on the Lewis Structure, differences in electronegativity, and the molecular geometry (shape).We start with the Lewis Structure and look and the polarity of the individual bonds in Butane based on the electronegativity difference between atoms. Examine the arrows in the Lewis dot structure. A molecule is polar if theres a significant difference in the electronegativity charges between elements.
