The geometry of a covalent molecule can be predicted using valence shell electron pair repulsion... See full answer below. The same logic can be applied to ammonia (107.0° HNH bond angle, with three N(~sp 3.4 or 23% s) bonding orbitals and one N(~sp 2.1 or 32% s) lone pair), the other canonical example of … Answer: $\begingroup$ This answer explains why $\ce{SF2}$ will have a bond angle close to $90^\circ$ and $\ce{OF2}$ will have a bond angle closer to $109.5^\circ$. 180° is the value of the bond angle in XeCl2. For similar reasons, $\ce{HOF}$ will have a bond angle closer to $109.5^\circ$. Corrosive to skin and eyes. The ? > bb"NSF" The structure of "NSF" is There is a lone pair on the "N" atom, a lone pair on the "S" atom, and there are three lone pairs on the "F" atom. The shape of molecules is determined by the number of electron domains around the central atom, and the fact how many of them are bonding. Water has a bond angle of 105º and oxygen diflouride has a bond angle of 103.8º, which cannot be explained by repulsion since fluorine is larger than hydrogen $[1]$.This is phenomenon is, however, explained by Bent's rule:. {/eq} reveals that the oxygen atom has four electron domains around it. I am sure it is not the actual angle. As the lone pair-bond pair repulsion increases, the bonding angle increases. This is an "AX"_2"E" molecule, so the electron geometry is trigonal planar and the molecular shape is bent.
