2017年6月27日 · 1.立体构型、空间构型、几何构型一般 都是指分子各基团在空间中的分布（不包括孤对电子）和分子的具体形状。 例如我们熟知的甲烷是正四面体型，有时也要提及键长键角。 这些名词我看很多教科书上都是互换着用的。 2.VESPER是价层电子对互斥模型的英文缩写， 是用于推导分子理想空间构型的理论模型。 VESPER认为，分子中的价层电子对总是尽可能地互斥，均匀地分布在分子中。 因此，价层电子对的数目决定了一个分子或离子中的价层电子对在空间 …

2023年6月19日 · Lewis electron structures predict the number and types of bonds, whereas VSEPR can predict the shapes of many molecules and polyatomic ions. We can use the VSEPR model to predict the geometry of most polyatomic molecules and ions by focusing on only the number of electron pairs around the central atom, ignoring all other valence electrons present.

2010年8月8日 · Las moléculas con cuatro pares enlazantes y una solitario se disponen en forma de bipirámide trigonal. Sin embargo, al quitar el par solitario se obtiene una especie de tetraedro distorsionado. Una molécula que presenta esta distribución espacial de grupos es el tetrafluoruro de azufre, SF 4.

2010年8月8日 · Observe how in the molecular model the axial sulfurs are bent to the right, due to the repulsions with the lone pair. In the proposed geometry, the para solitaire occupies the equatorial position, undergoing repulsions with two bonding pairs (axial) that are at 90º.

Learn molecular geometry with VSEPR theory. Covers shapes, bond angles, hybridization. Ideal for chemistry students.

According to this theory, the molecular shape depends on the repulsion between the valence shell electron pairs of the central atom. The electron pairs will rearrange themselves to minimize the repulsion. It is only possible when they are as far apart as possible.

There are no stable ABE4, AB3E3, AB2E4 or ABE5 molecules. All bonds are represented in this table as a line whether the bond is single, double, or triple. Any atom bonded to the center atom counts as one domain, even if it is bonded by a double or triple bond. Count atoms and lone pairs to determine the number of domains, do not count bonds.

Atoms that have expanded octets have AB5 (trigonal bipyramidal) or AB6 (octahedral) electron domain geometries. Trigonal bipyramidal structures have a plane containing three electron pairs. F P The fourth and fifth electron pairs are located above and below this plane. In this structure two trigonal pyramids share a base.

2023年10月21日 · A molecule represented as AB4E, with 4 bond pairs and 1 lone pair, adopts a trigonal bipyramidal electron-pair and a see-saw molecular geometry. The lone pair occupies an equatorial position, and the bond angle is less than 109.5°, specifically 104.5°, to minimize electron pair repulsion.
