What is the Lewis structure of F2O?

Answer 1

Difluorine monoxide, or oxygen difluoride, has OF2 for its chemical formula. Has one of the lowest melting points of any compound, 30 K. Has been used as a biological medium in the SF novel Camelot 30K by Robert Forward, for life on a planetoid in the Oort Cloud.

Answer 2

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.

Answer 3

To figure out the Lewis dot structure, look at the valence electrons. These are electrons in the outermost shell.

1. Figure out the group it is in at the Periodic Table or figure out its configuration electron.. *v=valence electrons

Alkali Metals: 1v*

Alkaline Earth Metals: 2v

Groups 3-5, 7-10, 12: 2v

Groups 6 and 11: 1v

Group 13: 3v

Group 14: 4v

Group 15: 5v

Group 16: 6v

Group 17: 7v

Group 18: 8v

Fluorine : Group 17, Halogens: 7 valence electrons

Electron Configuration: 1s2 2s2 2p6 3s2 3p5

Shell Electrons: 2, 8, 2

2. The valence electrons are the number of dots you draw around the chemical symbol, in this case, Fluorine or F

So, the symbol is 7 dots around F.

Also keep in mind that fluorine is a diatomic ion which means that the should be F2

Answer 4

The Lewis structure of F2O has a single bond between each fluorine atom and the oxygen atom, with two lone pairs on the oxygen atom. This arrangement allows each atom to satisfy the octet rule and minimizes formal charges.

Answer 5

FOF with six x's on each side of the fluorine atoms and eight x's around the oxide atom.

Answer 6

Cl-O-Cl

o with 2 electrons on top and bottom and Cl each with 2 electrons on the sides not bonded with O

Answer 7

f-
