What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
How do you determine the type of hybridization of the central atom by relating it to the molecular geometry?
check valence electron
What is the molcular geometry of NH4?
The molecular geometry of NH4+ is tetrahedral. This is because NH4+ has four bonding regions (four hydrogen atoms bonding with the central nitrogen atom) and no lone pairs of electrons on the central nitrogen atom.
How do you determine the molecular geometry of a molecule?
The molecular geometry of a molecule can be determined using the VSEPR theory. VSEPR (Valence Shell Electron Pair Repulsion) Theory: The basic premise of this simple theory is that electron pairs (bonding and nonbonding) repel one another; so the electron pairs will adopt a geometry about an atom that minimizes these repulsions. Use the method below to determine the molecular geometry about an atom. Write the Lewis dot structure for the molecule. Count the number of things (atoms, groups of atoms, and lone pairs of electrons) that are directly attached to the central atom (the atom of interest) to determine the overall (electronic) geometry of the molecule. Now ignore the lone pairs of electrons to get the molecular geometry of the molecule. The molecular geometry describes the arrangement of the atoms only and not the lone pairs of electrons. If there are no lone pairs in the molecule, then the overall geometry and the molecular geometry are the same. If the overall geometry is tetrahedral, then there are three possibilities for the molecular geometry; if it is trigonal planar, there are two possibilities; and if it is linear, the molecular geometry must also be linear. The diagram below illustrates the relationship between overall (electronic) and molecular geometries. To view the geometry in greater detail, simply click on that geometry in the graphic below. Although there are many, many different geometries that molecules adopt, we are only concerned with the five shown below.
What is the electron-domain geometry of PF6?
The electron-domain geometry of PF6 is Octahedral, since the central atom Phosphorus has an electron pair geometry which is octahedral
What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What is the difference between Electron Geometry and Molecular Geometry and explain the circumstances under which they will not be the same?
Electron geometry describes the arrangement of electron pairs around a central atom in a molecule, based on the total number of electron pairs (bonding and nonbonding). Molecular geometry, on the other hand, describes the arrangement of atoms, taking into account only the positions of the atoms. They will not be the same when there are lone pairs of electrons on the central atom. In such cases, the electron geometry is determined by all electron pairs, whereas the molecular geometry considers only the positions of the atoms, leading to a difference.
What is the electron domain geometry of BrF3?
The electron domain geometry of BrF3 is T-shaped. It consists of two bonding domains and three lone pairs of electrons around the central bromine atom, resulting in a T-shaped molecular geometry.
What is the electron pair geometry around the central atom of SeF6?
electron pair geometry: octahedral molecular geometry: octahedral
Clf4- square planar b clf4 plus linear c no2- t-shaped d brf3 bent e co2 s?
a) ClF4- has a square planar geometry due to its five electron domains, with four bonding pairs and one lone pair. b) ClF4+ has a linear geometry with no lone pairs, resulting in a linear molecular shape. c) NO2- has a T-shaped geometry with three electron domains - one lone pair and two bonding pairs. d) BrF3 has a bent molecular geometry due to the presence of two lone pairs and two bonding pairs around the central atom. e) CO2 has a linear molecular geometry as it has two electron domains and no lone pairs around the central carbon atom.
What is the molcular geometry of NH4?
The molecular geometry of NH4+ is tetrahedral. This is because NH4+ has four bonding regions (four hydrogen atoms bonding with the central nitrogen atom) and no lone pairs of electrons on the central nitrogen atom.
How does the VSERP formula explain molecular shape?
Valence electron pairs will move as far apart from each other as possible. (Apex)

How do you determine the type of hybridization of the central atom by relating it to the molecular geometry?
check valence electron
How do you determine the shape of molecules?
The shape of molecules is determined by the number of bonding and non-bonding electron pairs around the central atom. The VSEPR (Valence Shell Electron Pair Repulsion) theory is commonly used to predict molecular geometry based on electron pairs' repulsion. The arrangement of these electron pairs results in different molecular shapes such as linear, trigonal planar, tetrahedral, and more.
What is the electron domain or shape of chloroform CHCl3?
The electron domain geometry of chloroform (CHCl3) is tetrahedral, while the molecular shape is trigonal pyramidal. This is due to the presence of three bonding pairs and one lone pair around the central carbon atom.
Why is the VSEPR model mainly?
The VSEPR (Valence Shell Electron Pair Repulsion) model explains molecular geometry based on the repulsion between electron pairs in the valence shell of an atom. It is mainly used because it is simple, intuitive, and provides a good approximation of molecular shapes based on the number of bonding and nonbonding electron pairs around a central atom.
