Polarity of Bonds:                                         Electronegativity Difference:

N-H: Moderately Covalent                           .8

C-H: Very Covalent                                       .3

C-N: Very Covalent                                       .5

C-O: Moderately Covalent                          1

C-F: Slightly Covalent                                 1.5

C-C: Completely Covalent                          0

The molecule above is a polar molecule. 

When reacted with itself the molecule experiences: London Dispersion Forces, Dipole-Dipole Forces, and Hydrogen Bonding.

London Dispersion Forces: A weak and temporary bond due to the uneven distribution of electrons that creates a temporary dipole. 

Dipol-Dipol Forces: An electrostatic attraction between the positive end of one molecule and the negative end of another molecule. 

Hydrogen Bonding: A special type of dipole-dipole, where Hydrogen makes a temporary bond with the Oxygen or Fluorine in the case of Fluorouracil.
