Explanation / Answer

Though Fluorine is more electronegative than carbon due to presence filled p orbitals it acts like an electron donating group. When a hydrogen of ethene is replaced with an electron releasing group the fluorine atom releases electrons toward the bond, raising the energy of the orbitals relative to ethene. The HOMO coefficients of the carbon proximal to the fluorine are diminished, whereas the orbital density of the distal carbon is increased.
