You can look at the atoms like puzzle pieces where you are trying to fit together the electrons so that everyone that needs an octet has one. In this example, carbon is the central atom. Hydrogen atoms will come off each side of the carbon. Each hydrogen atom must have two electrons. Carbon will have eight total electrons, meaning it has four bonds and no lone pairs.

Based on the Lewis structure above the AXE notation would be AX 4 E 0, meaning there are a total of four substituents 4 atoms and 0 lone pair coming off of the central atom.

The geometry of the molecule can be described in two ways: 1 Electron Geometry—the geometry that takes lone pairs and atoms into account hint: there is are only 5 different electron geometries and 2 Molecular Geometry— the geometry that ignores lone pairs and only takes atoms into account there are 13 of these. A frequently asked question with VSEPR is whether or not a student should memorize the different molecular geometries an atom could take.

A good rule of thumb is to determine the electron geometry first then assume that any lone pairs of electrons are along the equator of the central atom. CH 4 molecular geometry is tetrahedral.

While understanding what matter is made of, we learn about so many new things that we simply lose ourselves in the beautiful world of chemistry. However, a few concepts can be slightly difficult to comprehend because they seem similar or because they are just confusing!

One such concept is the difference between electron geometry and molecular geometry. To help you out, we are shedding light on electron geometry vs molecular geometry in this article. Electron geometry teaches us about the arrangement of different electron groups. Molecular geometry, on the other hand, helps us understand the entire atom and its arrangement.

It is the 3D arrangement of all the atoms in a particular molecule. So, when you compare them, you will note that atoms have different arrangements in electron geometry and molecular geometry.

What Is the Molecular Geometry of CH4?

We consider both lone electron pairs and bond electron pairs while determining the shape of a molecule in electron geometry. In molecular geometry, though, we only consider bond electron pairs. We calculate the number of total electron pairs in electron geometry and not in molecular geometry. Through electron geometry, we get the spatial arrangement of the lone pairs and bond in the molecule.

The central atom here is C, and there are 4 valence electrons. Hydrogen atoms donate 4 electrons, which means there are a total of 8 electrons around C. The single bonds, in this case, are 4 and the number of lone pairs is 0. Oxygen is the central atom here with 6 valence electrons. Hydrogen donates a total of 2 electrons, making the total 8. So there are 4 electron groups and 2 lone electron pairs. There are also 2 single bond pairs.

Thus, the molecular geometry here is bent. We hope you now clearly understand how electron geometry and molecular geometry are different, and how they can help us understand the world of molecules and atoms better. We encourage you to take more examples and try determining the geometries yourself to grasp the concept further. All the best! Your email address will not be published. Electron Geometry vs Molecular Geometry 1. In such a way we can draw the structure of different molecules quite easily.

It is a tetrahedral. If it has 4 single bonds, like in this case, it is sp3 hybridized and has a molecular geometry of tetrahedral. An example is CH4. Electron group arrangment and molecular geometry is same. It is tetrahedral in shape.It is a group hydride and the simplest alkaneand is the main constituent of natural gas.

The relative abundance of methane on Earth makes it an attractive fuelalthough capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloorand is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphereit is known as atmospheric methane.

Methane is a tetrahedral molecule with four equivalent C—H bonds.

Its electronic structure is described by four bonding molecular orbitals MOs resulting from the overlap of the valence orbitals on C and H. The lowest energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the four hydrogen atoms. Above this energy level is a triply degenerate set of MOs that involve overlap of the 2p orbitals on carbon with various linear combinations of the 1s orbitals on hydrogen.

The resulting "three-over-one" bonding scheme is consistent with photoelectron spectroscopic measurements. At room temperature and standard pressuremethane is a colorless, odorless gas. Solid methane exists in several modifications. Presently nine are known. This substance crystallizes in the cubic system space group Fm 3 m. The positions of the hydrogen atoms are not fixed in methane I, i. Therefore, it is a plastic crystal. The primary chemical reactions of methane are combustionsteam reforming to syngasand halogenation.

In general, methane reactions are difficult to control. Partial oxidation of methane to methanol is challenging because the reaction typically progresses all the way to carbon dioxide and water even with an insufficient supply of oxygen. The enzymes methane monooxygenase produces methanol from methane, but cannot be used for industrial-scale reactions.

These generally operate by generating protected products which are shielded from overoxidation. Examples include the Catalytica systemcopper zeolitesand iron zeolites stabilizing the alpha-oxygen active site. One group of bacteria drive methane oxidation with nitrite as the oxidant in the absence of oxygengiving rise to the so-called anaerobic oxidation of methane.

Like other hydrocarbonsmethane is a very weak acid. A variety of positive ions derived from methane have been observed, mostly as unstable species in low-pressure gas mixtures. Some of these have been detected in outer space. Methanium can also be produced as diluted solutions from methane with superacids.

Despite the strength of its C—H bonds, there is intense interest in catalysts that facilitate C—H bond activation in methane and other lower numbered alkanes. Methane's heat of combustion is Peters four-step chemistry is a systematically reduced four-step chemistry which explains the burning of methane. Given appropriate conditions, methane reacts with halogen radicals as follows:. This mechanism for this process is called free radical halogenation.
