Suppose that you want to test the effects of different dishwashing detergents on dishes that have food stuck to them. to test the differences, you wash three loads of the same dishes, each with a different type of detergent, all in warm water. you also wash a fourth load of dishes with only warm water. the independent variable in this experiment is the type of detergent used. true or false?

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
