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.
