It is important to know if a particular molecule is composed of elements with different electronegativities as well as the structure of the particular molecule to explain the physical properties (such as boiling/melting point, solubility, etc.) of the molecule. Fully explain why you need to know both the electronegativity of each element in the compound and the structure of the molecule to explain the molecule's physical properties.© BrainMass Inc. brainmass.com October 10, 2019, 5:35 am ad1c9bdddf
Electronegativity difference is important as it determines the polarity of a bond. Polar bonds can result in polar molecules depending on the structure. ...
