1:杂化形式不同，NH3为SP3杂化，为三角锥形，BH3为SP2杂化，为平面三角形 2：因为中心原子属于同一主族，在上述化合物中杂化形式相同，均为SP3，化学式类似，所以结构相似。3：还是因为杂化形式不同，后者是平面三角形，前者是三角锥 4：根据中心原子的杂化态，和配位原子数及孤对电子数来判断集合结构。
What is the molecular geometry of NH_3? What is the Lewis structure of CNO? What is the Lewis structure of NH3? What is the Lewis dot structure for CF4? What are degenerate orbitals? What is the Lewis structure for SiF4? What is CCl4's molecular geometry?
In this paper, the VSEPR theory is applied to interpret the e-lectronic structure of some mononuclear substance, such as Ne, F-, O2-, N3-and C4-. Based on the electronic structure of O2-, N3-and C4-, the bond angle difference of H2 O, NH3 and CH4 are further interpreted based on...
What is the Lewis structure of NH3? Why do non-bonded electrons help determine the shapes of molecules? Explain in detail. For the shape of BF3, why does B have only 6 electrons surrounding it if we draw the Lewis Dot...
We discuss the example of a simple molecular structure prediction for ammonia (NH3). Using the origami model, both molecular shape and the scientific justification can be visualized easily. This 'hands-on' approach to building m... 更多
The structure of the planar pentagonal ion XeF,-. atom A cannot be made with as much certainty as for mol- ecules in which there are six or fewer electron pairs in the valence shell because there are three electron pair arrange- ments with very similar interpair distances (Fig. 5). ...
Conformational and Bonding Analysis of 2 24 CH In this report, different models of bonding and structure such as Lewis, VSEPR, Ligand close packing (LCP), VB, qualitative MO and QTAIM have been applied to analyze the Bonds and structures of two equilibrium geometries (planar D2h and ... G...

In terms of molecular structure, what additional information does the VSEPR theory give you beyond electron dot structures? Use the VSEPR theory to predict the shape of hydrogen selenide (H2Se). Predict the shape of IF4+ on the basis of VSEPR theory. Predict the shape ...
“Secondary bonding is best thought of as incipient hypervalency and occurs when a main group element with an octet structure, EXx, interacts with the lone pairs of one or more neighbouring groups, Y, that bind weakly to E to give rise to E∙∙∙Y distances of intermediate length, ...
