Part B

What is the electronic geometry of H2O?

Enter the electronic geometry of the molecule.

Part C

What is the electronic geometry of ClF3?

Enter the electronic geometry of the molecule.

Part D

What is the electronic geometry of BBr3?

Answer 1

Concepts and reason

This problem is based on the Lewis structure. Lewis structure is a structure that shows the bonding between atoms of a molecule and lone pair of electrons that may present in the molecule is called as Lewis structure. Electronic geometry of a molecule can be determined using its Lewis structure.

Fundamentals

According to Lewis structure, each and every atom and their position in the structure of a molecule by using its chemical symbol. Lines connecting the atoms that are bonded to them are drawn. Lone pairs are represented by pairs of dots, and are located beside to the atoms.

The Lewis structure of is shown as follows:

Part B

The molecule has lone pairs on central atoms and hence it is bent.

Part C

The molecule has lone pairs on central atoms as shown below. Hence it is trigonal pyramidal.

Part D

The molecule has no lone pairs on central atoms as shown below. Hence it is trigonal planar.

Ans:

The Lewis structure of is shown as follows:

Part B

The electronic geometry of is bent.

Part C

The electronic configuration of is trigonal pyramidal.

Part D

The electronic configuration of is trigonal planar.
