What is the molecular geometry of a molecule with 2 outer atoms and 1 lone pair on the central atom?
The molecular geometry of this molecule is bent. Click on the related link for a Wikipedia article that contains a VSEPR table.
What is a visual model of molecular geometry?
VSEPR theory
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.
According to VSEPR theory an AB2 molecule is?
linear
How does VSEPR determine molecular geometry?
The VSEPR model has enabled chemists and students to describe, explain, and predict more easily the stereochemistry of chemical elements and compounds. The Lewis structure, which was primarily used to convey the appearance of molecules in the past, proved to be inadequate because there existed many exceptions to this type of diagram. The Lewis structure displayed no information about the geometry of a molecule as it did not indicate how atoms were arranged in space. The VSEPR theory has relieved chemists and students of such limitations by describing the orientation of a molecule in relation to the Pauli principle. By determining this principle affected molecular geometry, Gillespie illustrated that the repulsion interactions of all electron pairs, both shared and unshared ones, in the valence of a molecule determine its shape. This is due to the fact that electron pairs adapt an arrangement that keeps them as far apart as possible; they repel one another. glad to help grade 12 chem student
What does vsepr theory tell us about a molecule?
VSEPR predict the geometry of a chemical molecule.
How do you apply the VSEPR method to deduce the geometry of a molecule?
You memorize the different configurations/bond angles, and what geometry the produce. Or, simply look it up in a table.
What is the vsepr shape of THC?
THC (tetrahydrocannabinol) does not have a defined VSEPR shape as it is a molecule with a complex structure containing multiple rings and functional groups. The molecule is quite flexible, leading to variations in its geometry.

What is a visual model of molecular geometry?
VSEPR theory
What are repelled in the VSEPR theory?
Electron pairs
Is butane a molecule?
It is a hydrocarbon with the formula, C4H10
Which theory describes the way are arranged within a molecule?
the VSEPR theory
How the VSEPR effects bonding in compounds?
The VSEPR theory helps predict the molecular geometry of compounds by considering the repulsion between electron pairs around the central atom. This influences the angles and shapes of the molecule, which in turn affects the type of bonding present. For example, molecules with tetrahedral geometry usually have sp3 hybridization and form covalent bonds.
