took back british N. Sigdwick and H. Powell idea, and developped the theory of the valence shell electron pair repulsion VSEPR. ICl4-. AX6. AX5E. AX4E2
With five nuclei, the ICl4− ion forms a molecular structure that is square planar, an octahedron with two opposite vertices missing. The relationship between the number of electron groups around a central atom, the number of lone pairs of electrons, and the molecular geometry is summarized in Figure \(\PageIndex{6}\). Therefore, VSEPR theory predicts the carbonate ion will take a trigonal planar shape, with a 120° bond angle. Exceptions to VSEPR Theory Valence Shell Electron Pair Repulsion theory does not always predict the correct geometry of molecules. repulsiones de pares electrónicos de la capa de valencia: PCl3, ICl4-, ICl2+, XeOF4, XeO3, SF4, ClF3, ICl2-, OSF4, POCl3, XeO2F2, XeO2, IOF5, IO2F2-, IF4-PCl 3: 1 ps+3 pe= 4.

Looking at the NO2 - Lewis structu 化学の分子の形について教えてください。CCl4, XeF4, SO2, ClF3, O3, SF4 の分子の形、そして予測される結合の角度をそれぞれ答えなければなりません。たとえば直線型とか、折れ線型、正四面体型 などです。角度は、90度だとか109.5度とかです。CO2やNH4などの頻繁に現れるものはだいたい覚えているの The VSEPR theory predicts that XeF₂ is linear. We must first draw the Lewis structure for XeF₂. This tells us that there are five electron regions (Steric Number = 5) about the central carbon atom. They are the three lone pairs and the two Xe-F bonds. The VSEPR model states that the electron regions around an atom spread out to make each region is as far from the others as possible.
CCl4 is tetrahedral, with C acting as the central atom and creating four bonds, one with each Cl. The Cl atoms are at maximum distance from each other, which creates the tetrahedral shape.

VSEPR SF 4 Sulfur Tetrafluoride. Sulfur tetrafluoride has 5 regions of electron density around the central sulfur atom (4 bonds and one lone pair). These are arranged in a trigonal bipyramidal shape with 102° F-S-F bond angles between the equatorial fluorine atoms and 173° between the axial fluorine atoms. What are the bond angles of ICl4?

VSEPR Theory (Molecular Shapes) A = the central atom, X = an atom bonded to A, E = a lone pair on A Note: There are lone pairs on X or other atoms, but we don't care.
