For a molecule of fluorous acid, the atoms are arranged as HOFO.

What is the formal charge on each of the atoms? Enter the formal charges in the same order as the atoms are listed.

(I searched everything online to find the shape of HOFO but could not find it--(they are wrong?!?))
(Could you please give me the correct Lewis structure?)(I know how to calculate formal charges: but have gotten wrong answers these past few hours) THANKS.

The formal charge is 0 on H and 0 on the O of HO. F is +1 and the right most O is -1.

If I draw the Lewis structure for HOFO, I count four regions of high electron density which translates to tetrahedral electronic shape; however, I can't find anything on the net or in my texts that will confirm that.

To determine the formal charge on each atom in a molecule, we need to consider the Lewis structure. Unfortunately, I am unable to provide images, but I can guide you through the steps to draw the correct Lewis structure for fluorous acid (HOFO).

1. Start by determining the total number of valence electrons. Fluorous acid consists of one hydrogen (H) atom, one oxygen (O) atom, and two fluorine (F) atoms. Hydrogen has 1 valence electron, oxygen has 6, and fluorine has 7 each. So, the total is 1 + 6 + 7 + 7 = 21 valence electrons.

2. Identify the central atom. In this case, since oxygen is more electronegative than hydrogen and fluorine, oxygen will be the central atom.

3. Connect the central atom to the surrounding atoms using single bonds. In this case, oxygen forms a single bond with each fluorine atom (O-F-F).

4. Distribute the remaining electrons in order to complete the octet for all atoms. Oxygen already has 8 electrons (2 from the bond and 6 lone pairs), so we move on to the surrounding atoms. Each fluorine atom requires 8 electrons to complete its octet, so we add 3 lone pairs (6 electrons) around each fluorine atom.

5. Place any remaining electrons on the central atom. If there are any remaining electrons, distribute them as lone pairs around the central oxygen atom.

6. Calculate the formal charge. The formal charge on an atom is calculated by subtracting the number of non-bonding electrons and half of the bonding electrons from its total number of valence electrons.

To verify your answer, follow these guidelines:

- The sum of all formal charges should equal the overall charge of the molecule (if any).
- The formal charge of an atom should be as close to zero as possible.
- If there is a negative formal charge, it should reside on a more electronegative atom, and if there is a positive formal charge, it should reside on a less electronegative atom.

I hope this helps you to draw the correct Lewis structure and calculate the formal charges for fluorous acid (HOFO).
