How would you draw the Lewis Dot Structure for H2CF2?

Answer 1

 When drawing Lewis structure to be valid, each atom must have a full octet of 8 electrons (except hydrogen, which only has a duet of 2 electrons). The structure with both of the hydrogens and both of the fluorines bonded to the carbon allows all atoms to have the proper number of electrons (if the lone pairs on the fluorine atoms are included). In the structure below, fluorine has six electrons in three lone pairs (not drawn) and the seventh electron participating in a covalent single bond to the Carbon, which allows the Fluorine to have an octet. Likewise, the carbon achieves its octet by sharing bonds with the two F and two H allows. Hope this helps.
