What is the Lewis dot structure of CH2F2?

Answer 1

Carbon is the middle atom, there are no double bonds you just add the 4 other atoms around it in a tetrahedral structure (if you haven't done this yet don't worry about it)

hope that works out :S

Answer 2

CH2F2 is a hydrofluorocarbon. If you put the carbon in the middle and put one valence electron each on the left, right, top, and bottom, then bond the H's and F's to each of those four sides, you will find that your Lewis structure works. Remember, H has 1 valence electron and F has 7. Carbon will need to share to get 8, along with the fluorines. H only needs 2. All your bonds will be single covalent, with unshared electrons on the flouorine sides, making it a polar covalent molecule.

Answer 3

The dot structure arranges the electrons around its central nucleus.
