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.
The above answer is incorrect. The correct answer is that AlCl3 is non polar, even though it is trigonal planar the atoms are spread symetrically making it non-polar!hey may be classified as polar and non-polar. A non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline.
