Is SF₂ angular because it is like an H₂O molecule where the there are 4 sp³ hybrid  orbitals and the unbonded pairs of electrons in 2 sp3 orbitals repel each other more so than the bonded electrons making it an angular molecule?

Or, do the fluorines just bond to the 3p_y and 3p_z orbitals?  If this is the case, what would make the molecule angular?

Thanks

The oxygen has 2 Hydrogens attached to it and it has 2 pairs of non-bonding electrons for a total of 4 things around the oxygen. The most likely way to arange 4 things around any object would be to have everything on the same plane or in a tetrahedron. To maximize the distance between 2 non-bonding electron pairs it will assume a tetrahedral shape.

H₂O is not a tetrahedron really though.  I mean it is but it is not symmetrical.  I understand the bond angle of H₂O is 104.5.  I just can't figure out why SF2 is angular because it is like H2O or for another reason.

Because its like H2O

Thanks Mitch    Is that what you were trying to tell me in the first place but I was too thick to figure it out?  If so, sorry.

[Mitch]

Yeah, basically.
