Question

how does electronegativity and molecular size influence the bonding and intermolecular forces in a pure substance and solution?

Answer 1

Answer:

n the microcosm of a general chemistry class, electronegativity can help determine the presence of dipole moments along a bond and determine polarity for the overall molecule based on geometry. Polar molecules have stronger intermolecular forces (like H bonding and dipole-dipole interactions) than non-polar molecules. Polar molecules also tend to dissolve in polar solvents, like water. I'm guessing that's where solutions come in. Even non-polar molecules have intermolecular forces, though. London dispersion forces exist for all molecules (polar and non-polar) but are more pronounced for large molecular weight (and by extension, size) compounds versus small molecules.
