What is the VSEPR theory, and how can it be used to predict the shape of molecules? Provide an example using small molecules such as carbon tetrachloride (CCl4), acetone (CH3COCH3), carbon dioxide (CO2), sulfur hexafluoride (SF6), or ammonia (NH3). Following the VSEPR theory, what...
Lewis structure of NH3 Each multiple bond (i.e. double bonds, triple bonds) constitutes a single electron domain. For example, carbon dioxide or CO2 contains two electron domains around the central carbon atom – two bonding pairs as shown by each double bond. Figure 3-2. Lewis structure ...

A trigonal pyramidal molecule like NH3 is an example. Due to electron-electron repulsion, the lone pair on the central nitrogen atom forces the three N-H bonds downward in the ammonia molecule. Seesaw SF4 is an illustration of a seesaw-shaped molecule. Two of the S-F bonds in an SF4 mol...

Thus, using valence bond theory, we would describe the bonds in methane as follows: each of the carbon sp3 hybrid orbitals can overlap with the 1s orbitals of a hydrogen atom to form a bonding pair of electrons. This shape is called tetrahedral. H2O Oxygen: NH3 This shape is called be...
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
