## How To Determine Molecular And Electronic Geometry?

Steps Used to Find the Shape of the Molecule

1. Draw the Lewis Structure.
2. Count the number of electron groups and identify them as bond pairs of electron groups or lone pairs of electrons.
3. Name the electron-group geometry.
4. Looking at the positions of other atomic nuclei around the central determine the molecular geometry.

## How do you determine electron pair geometry?

The shape of a molecule can be predicted based on the number and arrangement of electron pairs around a central atom. The geometry is determined by minimizing the repulsions between electron pairs in the bonds between atoms and/or lone pairs of electrons as postulated by VSEPR theory.

## What is the difference between molecular and electronic geometry?

The molecular geometry definition in chemistry is the arrangement of atoms in relation to a central atom in three-dimensional space. Electron geometry is the arrangement of electron groups.

## What are the 6 basic molecular shapes?

The 6 basic molecular shapes are linear, trigonal planar, angular (bent), tetrahedral, trigonal pyramidal, and trigonal bipyramidal.

## Is molecular geometry shape?

Molecular geometry is the 3-dimensional shape that a molecule occupies in space. It is determined by the central atom and the surrounding atoms and electron pairs.

## What is the difference between molecular geometry and molecular shape?

The key difference between shape and geometry of a molecule is that shape of a molecule is the structure of the molecule excluding the lone pair on the central atom whereas the geometry of a molecule describes the arrangement of lone pair and bond pair electrons around the central atom of the molecule.

## What is the relationship between electron geometry and molecular geometry?

Re: Difference between molecular and electron geometry? Electron geometry describes the arrangement of electron groups. Molecular geometry describes the arrangement of atoms, excluding lone pairs. For example, in the case of a trigonal planar shape as defined by electron geometry, there are three bonds.

## When determining the molecular electron geometry of a molecule What information is required?

There are three basic steps to determining the molecular shape of a molecule: Write the Lewis dot structure of the molecule. That gives you the steric number (SN) — the number of bond pairs and lone pairs around the central atom. Use the SN and VSEPR theory to determine the electron pair geometry of the molecule.

## Are there any circumstances under which the molecular geometry is the same as the electronic geometry elucidate your reasons with examples?

The electron geometry and the molecular geometry are the same when every electron group bonds two atoms together. The presence of unbonded lone pair electrons gives a different molecular geometry and electron geometry.

## What are the types of molecular geometry?

Molecular Geometries. The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

## What is the molecular geometry of PH3?

The molecular geometry of PH3 is trigonal pyramidal. We start with the Lewis structure of PH3. The molecule has eight valence electrons. Phosphorus

## What is electron group geometry?

Electron group geometry is the three-dimensional arrangement of atoms in a molecule. The geometry of a molecule is an important factor that affects the physical and chemical properties of a compound.
