To find the correct oxidation state of Br in BrF5 (Bromine pentafluoride), and each element in the molecule, we use a few rules and some simple math.First, since the BrF5 molecule doesn’t have an overall charge (like NO3- or H3O+) we could say that the total of the oxidation numbers for BrF5 will be zero since it is a neutral molecule.We write the oxidation number (O.N.) 35, 46, 81 b. So 4 plus 28 equals 32 total valence electrons. Transcript: This is the CBr4 Lewis structure: Carbon Tetrabromide. B) 4. Give its one use 11. This is Dr. B.
