Problem: Each of the following ball-and-stick models shows wrong electron and molecular geometry of a generic molecule.Provide the correct molecular geometry for (b), given the number of lone pairs and bonding groups on the central atom.

FREE Expert Solution

We have to provide the correct molecular geometry for the molecule (b) in the diagram.


The molecular geometry of a molecules is a name for the three-dimensional arrangements of atoms in a molecule.


The molecular geometry for a molecule can be determined using the VSEPR model. The VSEPR model uses the AXE notation.

A = central atom

X = bond pairs/corner atoms

E = lone pairs on the central atom

Problem Details

Each of the following ball-and-stick models shows wrong electron and molecular geometry of a generic molecule.The figure depicts three ball and stick models. Figure a has one lone pair of electrons and three atoms bonded to a central atom. Figure b has one lone pair and four atoms bonded to a central atom. Figure c has two lone pairs and four atoms bonded to a central atom.

Provide the correct molecular geometry for (b), given the number of lone pairs and bonding groups on the central atom.
