The function name tells Excel what calculation to perform. The arguments are contained inside round brackets.
Best Answer: Look for molecular symmetries. Symmetrical molecules such as methane, carbon dioxide, carbon disulfide, and borane (BH3) are nonpolar. Asymmetric molecules such as water, ammonia, and acetone are polar.
Indicate in the column labeled âMolecular Polarityâ whether the molecule is polar or nonpolar. In the column labeled âBond Polarityâ indicate whether any of the bonds in the molecule are polar or if they are all nonpolar.(Leave the third column blank for now.ndicate in the column labeled âMolecular Polarityâ whether the molecule is polar or nonpolar.
