Consider the assumption that the four molecules of interest have approximately the same molar mass and very similar polarizabilities such that the magnitude of the dispersion forces should be about the same. this assumption allows us to use the data for pentane to account for the dispersion forces in the other three samples. based on your data and observations, is the assumption valid? why or why not? how has this assumption affected your data evaluation of intermolecular forces in the summary section? discuss polarizability, polarity, and relative imfs as part of your answer
