Intramolecular bonds refer to the covalent bonds holding molecules together and are many fold stronger than the weaker intermolecular forces of attraction between molecules. The strength of intermolecular forces between molecules is inversely proportional to the thermal energy of the system. Vibrational and...
Why is water such a good solvent? The answers have to do with … Intermolecular forces Intermolecular Forces 12/10/99 Intermolecular Forces There are 2 types of attraction in molecules: intramolecular bonds & intermolecular forces We have already looked at intramolecular bonds (ionic, polar, non-p...
*The closer the ion and dipole, the stronger the attraction 2.) The charge on the ion. *The higher the ion charge, the stronger the attraction. 3.) The magnitude of the dipole. *The greater the magnitude of the dipole, the stronger the attraction Effects of intermolecular forces 1.) ...

Molecules are electrically neutral overall but organize themselves by attractions of head to tail dipole orientation 4 Force of attraction between molecules is a dipole-dipole attraction 4 Dipole-dipole forces are smaller than ion- ion forces H vap. 20 kJ/mol ...
Dispersion forces An instant later the electrons in the left-hand molecule may well have moved to the other end. In doing so, they will repel the electrons in the right hand one. δ+ δ- δ- δ+ Dispersion forces The polarity of both molecules reverses, but you still have attraction. ...
