The methyl fluoride
Fluorine, which i the most electronegative element will pull the electron density of carbon toward it, creating a partial negative charge on fluorine and a partial positive charge on carbon as is represented below:
This polar bond will have a net dipole moment that will not cancel out, since the
For such a molecule, the possible intermolecular interactions are:
- London Dispersion Force (LDF).
- Dipole - Dipole Interactions (DD).
Note, that, in this case DD is stronger than LDF and therefore, the main intermolecular interactions is the dipole-dipole (DD).
