# of bonding groups/domains on ‘central’ atom # of lone pair electrons on ‘central’ atom Electron-pair Geometry
2 3 trigonal bipyramidal
6 octahedral
5 1 octahedral
4 2 octahedral


What are the 6 basic molecular shapes?

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

What are the electron domains geometry?

Electron domain geometries are one of the five learned so far: linear, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral. However, when one or more of the bonding pairs of electrons is replaced with a lone pair, the molecular geometry, or actual shape of the molecule, is altered.

How does Vsepr theory explain the electron group geometry of a molecule?

The premise of VSEPR is that the valence electron pairs surrounding an atom tend to repel each other and will, therefore, adopt an arrangement that minimizes this repulsion. This in turn decreases the molecule’s energy and increases its stability, which determines the molecular geometry.

What is the electron and molecular geometry for a molecule with 6 bonding domains and a single lone pair?

According to VSEPR theory the molecule with six binding domains and single lone pair will have the pentagonal bipyramidal geometry.

What is electron-pair geometry vs molecular geometry?

The main difference between electron geometry and molecular geometry is that electron geometry is found by taking both lone electron pairs and bonds in a molecule whereas molecular geometry is found using only the bonds present in the molecule.

What is molecular geometry in chemistry?

Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom.

How do you find the molecular geometry of an electron?

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.

Which of the following molecule will exhibit tetrahedral geometry?

Explanation: Ammonia exhibits a tetrahedral electron pair geometry. It has three bonded pairs (between nitrogen and each hydrogen), and one lone pair (on nitrogen).

What is electron domain theory?

An atom’s electron domain is the number of lone pairs or chemical bond locations that surround it. It represents the number of locations expected to contain electrons. By knowing the electron domain of each atom in a molecule, you can predict its geometry.

What is the molecular geometry of a molecule with 5 electron domains and two lone pairs?

2 Lone Pairs These are of the form of AX3E2 have trigonal bipyramidal electronic geometry and “T-shaped” molecular geometry. Bromine triflouride (BrF3) is an example of a molecule with 5 electron domains and two lone pairs (Figure.

Which of the following has trigonal planar geometry?

Structure of boron trifluoride, an example of a molecule with trigonal planar geometry.

What is the molecular geometry of a molecule with 4 groups attached to the central atom?

A molecule with four electron groups about the central atom orients the four groups in the direction of a tetrahedron, as shown in Figure 9.3 ” Tetrahedral Geometry”. If there are four atoms attached to these electron groups, then the molecular shape is also tetrahedral.

What molecular geometry would ph3 have?

In essence, ph3 is a Drago molecule and if we look at its bond angle data it shows that the p-orbitals have an angle of 90°. Looking at its Lewis structure we can state that molecular geometry of PH3 is trigonal pyramidal.
