What circumstances is the molecular geometry around a central atom the same as the electron group geometry around the central atom?
The molecular geometry around a central atom is the same as the electron group geometry when there are no lone pairs of electrons on the central atom. In such cases, all electron groups (bonding pairs) are arranged symmetrically around the atom, leading to identical geometries. This typically occurs in molecules with linear, trigonal planar, or tetrahedral arrangements, depending on the number of bonding pairs.
Determine the number of electron groups around the central atom for H2S?
There are two electron groups around the central sulfur atom in H2S. This gives H2S a bent molecular geometry.
What is the difference between Electron Geometry and Molecular Geometry and explain the circumstances under which they will not be the same?
Check the link, it is a sheet describing the different types of electron and molecular geometry. It helped me a lot. ^^ electron pair geometry and molecular geometry won't be the same if there are lone pairs involved.
What is the a in vsepr formula?
In VSEPR theory, the "a" stands for the number of atoms bonded to the central atom. It helps determine the molecular geometry by considering the number of bonding pairs and lone pairs around the central atom.
How do grups of electrons arrange themselves around the central atom according to VSEPR theory?
In VSEPR theory, electron groups (bonding pairs and lone pairs) around a central atom arrange themselves in a way that minimizes repulsion, resulting in various molecular geometries such as linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The number of electron groups around the central atom determines the molecular geometry.
What is the number of lone pairs around the central atom and the molecular geometry of CBr4?
There are no lone pairs and it's tetrahedral.

How can one predict molecular geometry?
One can predict molecular geometry by considering the number of bonding and non-bonding electron pairs around the central atom, using VSEPR theory. The arrangement of these electron pairs determines the shape of the molecule.

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 process of determining the molecular geometry of a molecule without using a Lewis structure?
One way to determine the molecular geometry of a molecule without using a Lewis structure is by using the VSEPR theory. This theory helps predict the shape of a molecule based on the arrangement of its atoms and lone pairs. By considering the number of bonding pairs and lone pairs around the central atom, you can determine the molecular geometry.

What is the difference between a tetrahedral and trigonal planar molecular geometry?
The main difference between tetrahedral and trigonal planar molecular geometries is the number of atoms bonded to the central atom. In a tetrahedral geometry, there are four atoms bonded to the central atom, arranged in a three-dimensional shape resembling a pyramid with a triangular base. In a trigonal planar geometry, there are three atoms bonded to the central atom, arranged in a flat, triangular shape.

In VSEPR theory, electron groups (bonding pairs and lone pairs) around a central atom arrange themselves in a way that minimizes repulsion, resulting in various molecular geometries such as linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

Do CO2 and so2 have the same geometry?
No, the geometry of CO2 is linear while the geometry of SO2 is bent.
How does molecular shape effect polarity?
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
