Â© Ted French. Definition: A function is a preset formula in Excel and Google Spreadsheets. Like formulas, functions begin with the equal sign (=) followed by the function's name and its arguments. 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.
NON-POLAR SOLUTE-NON-POLAR SOLVENT: In all types of non-polar compounds, about the only intermolecular attractions are the very weak induced dipole forces. The weak attractive forces formed by the solute-solvent molecules compensate for breaking those weak bonds in the two pure non-polar substances.
