Hi,
I am a chemistry student in a university and this is what i learn't in the class.
OF2 -
O has 6 electrons in outer shell and F has 7 in its outer shell
Therefore, you have to account for 20 electrons total in the
structure (7+7+6 = 20)
therefore draw it linear first. F ---- O-----F
The two bonds take care of 4 electrons now you have to add another 16.
Therefore 3 lone pairs on each F and 2 lone pair on O.
If you check for formal charges, all the atoms are neutral
F will have 3 lone pairs + 1 bond = 7 electrons (bond = 1/2 electron for formal charge distribution) therefore both the F's are neutral
Now look at the O: it should have 6.. it has two lone pair and 2 bonds = 4 electrons and 2 bonds = 1 electron each = 2 electrons from bonds = 6 total electrons for formal charge which is exactly the # it should have. There is no need for any double bond in this as there are no charges to be separated.
Now if u look at the # of domains around O you will see if you include the lone pairs it has a sp3 hybridization (4 domains) therefore a tetrahedron which has 2 lone pairs and 2 bonds.. since there are two lone pairs, the lone pair/bond pair repulsion is so high it is going to repel the two Fluorines and form a bent structure, looks a lot like H2O.
Again i am taking chemistry also and This is from my limited knowledge. Please do correct me if I am wrong.
Yes it is bent, with 105 degree bond angle
The oxidation number for oxygen in most compounds is -2. Since there are two oxygen atoms in F2O, this gives a total charge of -4. Therefore, the oxidation number for each fluorine atom in F2O is +2 to balance out the overall charge to zero.
Resonance structure.
The Lewis dot structure for germanium (Ge) is: Ge: :Ge:
The Lewis structure of the compound CCLO is as follows: CCCl-O.

The formal charge of the NCO Lewis structure is zero.
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.
The Lewis structure was created by American chemist Gilbert N. Lewis in 1916. Lewis proposed using dots to represent the valence electrons of an atom in order to show how atoms bond together in molecules.
The molecular geometry of the BR3 Lewis structure is trigonal planar.
Sulfur can form a maximum of six bonds in a Lewis structure.
The bond angle in the CHCl3 Lewis structure is approximately 109.5 degrees.
The formal charge of sulfur in the SO2 Lewis structure is 0.
