Please note that "geometry" refers to the molecular or ionic geometry. A. The Lewis diagram for SeOF2 is: T :ö–Se- F: The electron-pair geometry around the Se atom in SeOF2 is There are lone pair(s) around the central atom, so the geometry of SeOF2 is B. The Lewis diagram for CH4 is: H | H-C-H 1 H The electron-pair geometry around the C atom in CH4 is There are lone pair(s) around the central atom, so the geometry of CH4 is

A stable triatomic molecule can be formed that contains one atom each of nitrogen, sulfur, and fluorine. Three bonding structures are possible, depending on which is the central atom: NSF, SNF, and SFN. (a) Write a Lewis diagram for each of these molecules, indicating the formal charge on each atom. (b) Often, the structure with the least separation of formal charge is the most stable.

7.30 The bond in HF is said to be polar, with the hydrogen carrying a partial positive charge. For this to be true, the hydrogen atom must have less than one electron around it. Yet the Lewis dot structure of HF attributes two electrons to hydrogen. Draw a picture of the electron density distribution for HF and use it to describe how the hydrogen atom can carry a partial positive charge. How can these two models of the HF bond (the electron density and the Lewis structure) seem so different and yet describe the same thing?
