How do intermolecular forces affect boiling
WebMar 13, 2014 · These intermolecular forces are made possible by a large difference in electronegativity values for two atoms bonded to each other. In water, the electronegativity difference between oxygen (3.5) and hydrogen (2.1) is 1.4 (3.5-2.1=1.4). This, and waters bent shape, make water a polar molecule. WebIntermolecular forces are mainly responsible for the physical characteristics of the substance. Intermolecular forces are responsible for the condensed states of matter. The …

For hydrogen bonding, atoms that can … WebMoving down the group, from fluorine to iodine, melting points and boiling points increase with increasing atomic size (or mass). This increase may be rationalized by considering how the strength of dispersion forces is affected by the electronic structure of the atoms or molecules in the substance.
WebWhen simple molecular substances melt or boil, it is these weak intermolecular forces that are overcome. The covalent bonds are not broken. Relatively little energy is needed to overcome the...
